django-business-time

The django-business-time python package permits to calculate timedelta considering the working hours.

In your settings.py file you can specify the flag

Because several companies are working also on saturday :(

You can specify also a list of datetime.date named HOLIDAYS and a list of datetime.time named BUSINESS_DAILY_TIME

BUSINESS_DAILY_TIME must have 4 items:

The start time (default = 9)
The start break time (default = 12)
The stop break time (default = 13)
The stop time (default = 17)

use as:

from business_time import business_timedelta

business_timedelta(dt1,dt2)

where dt1 and dt2 are 2 datetime.datetime objects and dt2 >= dt1

install with

pip install git+https://github.com/mariuccio/django-business-time.git

and then in your settings.py:

an example of settings to put in your settings.py can be:

WORK_ON_SATURDAY = False

BUSINESS_DAILY_TIME = [9, 12, 13, 17]

HOLIDAYS = [

    [2015, 1, 1], # New Year's Day

    [2015, 12, 25], # Christmas Day

]

If we don't want the lunch break we can put BUSINESS_DAILY_TIME[1]==BUSINESS_DAILY_TIME[2], for example:

BUSINESS_DAILY_TIME = [9, 12, 12, 17]
