Module for performing simple business day arithmetic; forked from python-bizdatetime
pip install bizdatim==0.2.0
ABOUT ===== python-bizdatetime is a simple library for performing business day arithmetic. KNOWN LIMITATIONS ================= Rotating weekends/holidays are not supported (e.g., two days working, third day off). Business hour arithmetic is not (yet) supported. DEFINITIONS =========== Weekend Weekly repeating non-business day. Weekend does not have to be at the end (or beginning) or the week. Weekends do not have to be consecutive days. Holiday Like weekend, holiday is a non-business day. Unlike weekend, holiday does not have weekly regularity. It is just a date. Holiday can coincide with weekend. Policy Is a (possibly empty) collection of holidays and holidays. All calculations are performed within a policy. SAMPLE USAGE ============ All business day arithmetic is performed in the context of policy:: from bizdatetime import * from datetime import date policy = Policy(weekends=(SAT, SUN), holidays=(date(2011,7,1),)) day = date(2011, 6, 29) # Wednesday print policy.add(day, 2) # add 2 business dates -> Monday after the long weekend print policy.biz_day_delta(date(2011, 7, 4), date(2011, 6, 30)) # one holiday, one weekend between The output of the above program will be:: datetime.date(2011, 7, 4) 1 Policy method docstrings contain more examples.
