I have only found question Convert Days and Time (Hours x Minutes x Seconds) to Time only on stackoverflow and that seems like it would help me out but it doesn't seem to totally apply to what I'm doing.
I'm writing a wage tracking program and need it to give me the total sum of all hour input. I've got a much smaller and abridged form of it to just work on this one aspect. It saves a lot of time as the main program requires all the individual start and end times to be input by the user. It is currently showing 2 days, 22:00:00 as on output whereas I ideally would prefer it to show 70:00, showing only the hours and minutes and getting rid of the unneeded second part.
import datetime
def time_diff(a, b): # Calculates time difference between start and finish
return b - a
start = '10:00'
mon_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
mon_fin = datetime.datetime.strptime(finish, '%H:%M')
mon_hours = time_diff(mon_start, mon_fin)
start = '10:00'
tue_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
tue_fin = datetime.datetime.strptime(finish, '%H:%M')
tue_hours = time_diff(tue_start, tue_fin)
start = '10:00'
wed_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
wed_fin = datetime.datetime.strptime(finish, '%H:%M')
wed_hours = time_diff(wed_start, wed_fin)
start = '10:00'
thu_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
thu_fin = datetime.datetime.strptime(finish, '%H:%M')
thu_hours = time_diff(thu_start, thu_fin)
start = '10:00'
fri_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
fri_fin = datetime.datetime.strptime(finish, '%H:%M')
fri_hours = time_diff(fri_start, fri_fin)
start = '10:00'
sat_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
sat_fin = datetime.datetime.strptime(finish, '%H:%M')
sat_hours = time_diff(sat_start, sat_fin)
start = '10:00'
sun_start = datetime.datetime.strptime(start, '%H:%M')
finish = '20:00'
sun_fin = datetime.datetime.strptime(finish, '%H:%M')
sun_hours = time_diff(sun_start, sun_fin)
total_hours = mon_hours + tue_hours + wed_hours + thu_hours + fri_hours + sat_hours + sun_hours
print(total_hours)
This:
def time_diff(a, b): # Calculates time difference between start and finish
return b - a
if a is datetime.datetime and b is datetime.datetime return datetime.timedelta object. You can use its .total_seconds method to get value in second, which then you might use for further calculations, for example
import datetime
total = datetime.timedelta(days=3,minutes=10)
total_minutes = int(total.total_seconds()//60)
hours, minutes = total_minutes // 60, total_minutes % 60
print(hours, minutes) # 72 10
Just use this print at the end:
print(
"{}:{:02d}".format(
total_hours.days * 24 + total_hours.seconds // 3600,
(total_hours.seconds // 60) % 60,
)
All the above solutions will work, but just wanted to share something from my side as well.
Code:
seconds = time_diff(a, b).total_seconds()
def convert(seconds):
mins, secs = divmod(int(seconds), 60)
hours, mins = divmod(mins, 60)
return f'{hours:02d}:{mins:02d}:{secs:02d}'
print(convert(seconds)) # Will print in HH:MM:SS format

I would like to write a function that calculate working business hours in python, to do that I don't like to define a class and use python ready function to calculate.
I tried with following code but the code is not working well. I need to modify the code and change it for the hour instead of minutes too.
Do you have any suggestion?
def getminutes(datetime1,datetime2,worktiming=[9, 17]):
day_hours = (worktiming[1]-worktiming[0])
day_minutes = day_hours * 60 # minutes in a work day
weekends=[6, 7]
# Set initial default variables
dt_start = datetime1.datetime # datetime of start
dt_end = datetime2.datetime # datetime of end
worktime_in_seconds = 0
if dt_start.date() == dt_end.date():
# starts and ends on same workday
full_days = 0
if dt_start in [6, 7]:
return 0
else:
if dt_start.hour < worktiming[0]:
# set start time to opening hour
dt_start = datetime.datetime(
year=dt_start.year,
month=dt_start.month,
day=dt_start.day,
hour=worktiming[0],
minute=0)
if dt_start.hour >= worktiming[1] or \
dt_end.hour < worktiming[0]:
return 0
if dt_end.hour >= worktiming[1]:
dt_end = datetime.datetime(
year=dt_end.year,
month=dt_end.month,
day=dt_end.day,
hour=worktiming[1],
minute=0)
worktime_in_seconds = (dt_end-dt_start).total_seconds()
elif (dt_end-dt_start).days < 0:
# ends before start
return 0
else:
# start and ends on different days
current_day = dt_start # marker for counting workdays
while not current_day.date() == dt_end.date():
if not is_weekend(current_day):
if current_day == dt_start:
# increment hours of first day
if current_day.hour < worktiming[0]:
# starts before the work day
worktime_in_seconds += day_minutes*60 # add 1 full work day
elif current_day.hour >= worktiming[1]:
pass # no time on first day
else:
# starts during the working day
dt_currentday_close = datetime.datetime(
year=dt_start.year,
month=dt_start.month,
day=dt_start.day,
hour= worktiming[1],
minute=0)
worktime_in_seconds += (dt_currentday_close
- dt_start).total_seconds()
else:
# increment one full day
worktime_in_seconds += day_minutes*60
current_day += datetime.timedelta(days=1) # next day
# Time on the last day
if not is_weekend(dt_end):
if dt_end.hour >= worktiming[1]: # finish after close
# Add a full day
worktime_in_seconds += day_minutes*60
elif dt_end.hour < worktiming[0]: # close before opening
pass # no time added
else:
# Add time since opening
dt_end_open = datetime.datetime(
year=dt_end.year,
month=dt_end.month,
day=dt_end.day,
hour=worktiming[0],
minute=0)
worktime_in_seconds += (dt_end-dt_end_open).total_seconds()
return int(worktime_in_seconds / 60)
How can I modify the code that works with the following input ?
getminutes(2019-12-02 09:30:00,2019-12-07 12:15:00,worktiming=[9, 17])
You can use pd.bdate_range(datetime1, datetime2) to compute the number of working days. When converting worktiming to a pandas datetime, it is easy to compute the difference (in seconds) between the two datetimes:
import pandas as pd
datetime1 = "2019-12-02 09:30:00"
datetime2 = "2019-12-07 12:15:00"
def getminutes(datetime1, datetime2, worktiming=[9, 17]):
d1 = pd.to_datetime(datetime1)
d2 = pd.to_datetime(datetime2)
wd = pd.bdate_range(d1, d2) # working days
day_hours = (worktiming[1] - worktiming[0])
day_minutes = day_hours * 60 # minutes in a work day
day_seconds = day_minutes * 60 # seconds in a work day
full_days = len(wd)
day1 = datetime1[:10]
day2 = datetime2[:10]
dt1 = pd.to_datetime(day1 + " " + str(worktiming[0]) + ":00")
dt2 = pd.to_datetime(day2 + " " + str(worktiming[1]) + ":00")
ex1, ex2 = 0, 0
if day1 in wd:
ex1 = max(pd.Timedelta(d1 - dt1).seconds, 0)
if day2 in wd:
ex2 = max(pd.Timedelta(dt2 - d2).seconds, 0)
total_seconds = full_days * day_seconds - ex1 - ex2
total_minutes = total_seconds / 60
total_hours = total_minutes / 60
return int(total_minutes)
print(getminutes(datetime1, datetime2))
Output: 2370
I'm looking for a cooldown timer for python, basically just to print days,hours,minutes,seconds left from a certain date.
Thanks very much!
You can get the counter with the help of time delta function.
import datetime
import time
future_date = datetime.datetime.now()+ datetime.timedelta(seconds=3)
while True:
curr_date = datetime.datetime.now()
rem_time = future_date - curr_date
total_seconds = int(rem_time.total_seconds())
if total_seconds > 0:
days, h_remainder = divmod(total_seconds, 86400)
hours, remainder = divmod(h_remainder, 3600)
minutes, seconds = divmod(remainder, 60)
print("Time Left: {} days, {} hours, {} minutes, {} seconds".format(days, hours, minutes, seconds))
time.sleep(1)
else:
break
sample output will be:
Time Left: 0 days, 0 hours, 0 minutes, 2 seconds
Time Left: 0 days, 0 hours, 0 minutes, 1 seconds
Try this. The module datetime is preinstalled on Python, I believe.
import datetime
while True:
print("\033[H\033[J")
present = datetime.datetime.now()
future = datetime.datetime(2022, 3, 31, 8, 0, 0)
difference = future - present
print(difference)
The format for datetime's future is: year, month, day, hour, minute, second.
Or, if you'd like to have user input:
import datetime
year = int(input('Enter the year of the end date: '))
month = int(input('Enter the month of the end date: '))
day = int(input('Enter the day of the end date: '))
hour = int(input('Enter the hour of the end date: '))
minute = int(input('Enter the minute of the end date: '))
second = int(input('Enter the second of the end date (a little tricky): '))
future = datetime.datetime(year, month, day, hour, minute, second)
while True:
print("\033[H\033[J")
present = datetime.datetime.now()
difference = future - present
if present >= future:
break
print(difference)
print('Time reached!')
You can use the seconds from a timedelta from subtracting two dates to calculate the days, hours, minutes and seconds like this:
from datetime import datetime
import time
totalSecs = 1 #So the while loop doesn't stop immidiately
while totalSecs > 0:
startDate = datetime.now() #Can be any date
endDate = datetime(2021, 12, 25)
delta = endDate - startDate
totalSecs = delta.total_seconds()
days = divmod(totalSecs, 86400)
hrs = divmod(days[1], 3600)
mins = divmod(hrs[1], 60)
seconds = divmod(mins[1], 1)
print("{:02d}:{:02d}:{:02d}:{:02d}".format(int(days[0]), int(hrs[0]), int(mins[0]), int(seconds[0]))) #Zero pad all the numbers
time.sleep(1) #Print every second.
Thank you all for your replies, i've done a mistake when i made the post. Is not from a date. Is a countdown in day,hours,minutes,seconds from a certain amount of seconds. Let's say i've got 31104000 seconds and i want to print how many days,hours,minutes,seconds left from that amount of seconds.
The code i've got now is a bit trivial and i can't print seconds in realtime.
def SecondToDHM(time):
if time < 60:
return "%.2f %s" % (time, SECOND)
second = int(time % 60)
minute = int((time / 60) % 60)
hour = int((time / 60) / 60) % 24
day = int(int((time / 60) / 60) / 24)
text = ""
if day > 0:
text += str(day) + DAY
text += " "
if hour > 0:
text += str(hour) + HOUR
text += " "
if minute > 0:
text += str(minute) + MINUTE
text += " "
if second > 0:
text += str(second) + SECOND
return text
import datetime
a = datetime.datetime.now()
"%s:%s.%s" % (a.minute, a.second, str(a.microsecond))
let us consider start time, end time and Break time as
models.py
class Records(TimeStampedModel):
date = models.DateField()
start_time = models.TimeField(default='08:30')
end_time = models.TimeField(default='08:30')
break_time = models.FloatField(default=0.5, help_text="(Hrs)")
views.py
def record_working hours(request):
records = Records.objects.filter(created_by__client=request.user.client)
now = timezone.now()
today = timezone.now().date()
week_start = today - timedelta(days=(today.weekday()))
date_list = [week_start + timedelta(days=x) for x in range(5)]
week_last = date_list[-1]
working_time = records.filter(date__gte=week_start,date__lte=week_last)
for record in records:
work_hours = record.start_time - record.end_time - record.break_time
return redirect(reverse('record_list'))
Hear i need to calculate total working hours for current week but i am getting the error as " type object 'datetime.datetime' has no attribute 'datetime'" and when i print my start time, end time and break time i am getting as
start_time = datetime.time(8, 30)
end_time = datetime.time(18, 30)
break_time = 0.5
And also calculate total working hours for that week of all records
So I'm trying to print the total hours in intervals between a start date and an end date in python as follows:
#app.route('/test/')
def test():
date_format = "%Y-%m-%d %H:%M:%S"
start_date_time = datetime.strptime("2018-10-16 07:00:00", date_format)
end_date_time = datetime.strptime("2018-10-18 22:00:00", date_format)
def daterange(start_date_time, end_date_time):
for n in range(int ((end_date_time - start_date_time).days)):
yield start_date_time + timedelta(n)
for single_date in daterange(start_date_time, end_date_time):
def get_delta(start_date_time, end_date_time):
delta = end_date_time - start_date_time
return delta
# Split time in hours
delta = get_delta(start_date_time,end_date_time)
for i in range(delta.days * 24 + 1): # THIS IS ONLY CALCULATING 24HRS FROM TIME GIVEN START TIME NOT TILL THE SELECTED END TIME SO I'M ONLY GETTING AN EXACT 24 HOUR RANGE
currtime = start_date_time + timedelta(hours=i)
print (currtime)
return ("done")
By This i'm only managing to get the first 24 Hours from the selected date, but I wish to keep on counting and get all hours till the selected end date.
You might be overthinking it.
from datetime import datetime, timedelta
date_format = "%Y-%m-%d %H:%M:%S"
start_date_time = datetime.strptime("2018-10-16 07:00:00", date_format)
end_date_time = datetime.strptime("2018-10-18 22:00:00", date_format)
def get_delta(l, r):
return abs(int((l-r).total_seconds())) / 3600
for h in range(int(get_delta(start_date_time, end_date_time))):
print((start_date_time + timedelta(0, h*3600)).strftime(date_format))
I want to write a program that allows the user to enter in a start time hour, end time hour, and number of divisions.
So they might enter 9, 10, and 4 which should mean a start time of 9:00AM, end of 10:00AM and to split the range 4 times, resulting in an output of 9:00, 9:15, 9:30, 9:45.
I've tried using the time module and datetime, but cannot get the addition of time to work. I do not care about date.
I can calculate the time split, but the actual addition to the start time is evading me.
I have a hodge-podge of code, and the following is mostly me experimenting trying to figure out how to make this work. I've tried adding the minutes, tried converting to seconds, delved into datetime, tried the time module, but can't seem to get it to work. There are plenty of examples of how to "add 15 minutes to now" but the issue is I don't want to start at the "now", but rather let the user decide start time.
Thank you.
time_start = "9"
time_end = "10"
time_split = "4"
if len(time_start) == 1:
time_start = "0" + str(time_start) + ":00"
else:
time_start = str(time_start) + ":00"
if len(time_end) == 1:
time_end = "0" + str(time_end) + ":00"
else:
time_end = str(time_end) + ":00"
print time_start
print time_end
s1 = time_start + ':00'
s2 = time_end + ':00'
FMT = '%H:%M:%S'
tdelta = datetime.strptime(s2, FMT) - datetime.strptime(s1, FMT)
divided = tdelta / int(time_split)
print tdelta
print divided
s3 = str(divided)
print "s1 time start: " + str(s1)
print "s2 time end: " + str(s2)
print "s3 time divided: " + str(s3)
ftr = [3600,60,1]
add_seconds = sum([a*b for a,b in zip(ftr, map(int,s3.split(':')))])
print "s3 time divided seconds: " + str(add_seconds)
print "time delta: " + str(tdelta)
EDIT: I did a small bit of research and found a much better solution that elegantly handles resolution to the millisecond. Please implement this code instead (though I will save the old code for posterity)
import datetime
start_time = 9 # per user input
end_time = 10 # per user input
divisions = 7 # per user input
total_time = end_time - start_time
start_time = datetime.datetime.combine(datetime.date.today(),datetime.time(start_time))
end_time = start_time + datetime.timedelta(hours=total_time)
increment = total_time*3600000//divisions # resolution in ms
times = [(start_time+datetime.timedelta(milliseconds=increment*i)).time()
for i in range(divisions)]
from pprint import pprint
pprint(list(map(str,times)))
# ['09:00:00',
# '09:08:34.285000',
# '09:17:08.570000',
# '09:25:42.855000',
# '09:34:17.140000',
# '09:42:51.425000',
# '09:51:25.710000']
If I were you, I'd do my math as raw minutes and use datetime.time only to save the results as something more portable.
Try this:
import datetime
start_time = 9 # per user input
end_time = 10 # per user input
divisions = 4 # per user input
total_minutes = (end_time-start_time)*60
increment = total_minutes // divisions
minutes = [start_time*60]
while minutes[-1] < end_time*60:
# < end_time*60 - increment to exclude end_time from result
minutes.append(minutes[-1] + increment)
times = [datetime.time(c//60,c%60) for c in minutes]
# [09:00:00,
# 09:15:00,
# 09:30:00,
# 09:45:00,
# 10:00:00]
