business-days

This is a handful of functions that make working with business days easier. In this context, "business days" are Monday thru Friday, excluding certain bank holidays.

Install

pip install business-days

Usage

import business_days

# Simple day manipulation.
two_business_days_ago = business_days.days_to_now(timezone.now(), 2)

# More complex business hour calculations.
# Mon 07:00 -> Mon 18:30 (expected: 8 business hours)
assertEqual(8 * 3600, business_days.business_timediff(
    datetime(2016, 10, 17, 7),
    datetime(2016, 10, 17, 18, 30),
).total_seconds())

See the tests for more examples.

Note about developing this: If you are going to release a new version, don't forget to tag the release as v0.x.y (or whatever) so that it's easy to refer to specific versions from requirements.txt files.
