A fast, efficient Python library for generating business dates inherited from float for fast date operations. Typical banking business methods are provided like business holidays adjustment, day count fractions. Beside dates generic business periods offer to create time periods like ‘10Y’, ‘3 Months’ or ‘2b’. Periods can easily added to business dates.

Example Usage

from datetime import date

from businessdate import BusinessDate, BusinessPeriod

>>> BusinessDate(20140101).add_days(10)
20140111

>>> BusinessPeriod('1Y').add_months(3)
1Y3M

>>> BusinessDate(20140101) + BusinessPeriod('1Y3M')
20150301

Install

The latest stable version can always be installed or updated via pip:

$ pip install businessdate

If the above fails, please try easy_install instead:

$ easy_install businessdate

Examples

# Simplest example possible

>>> from datetime import date
>>> from businessdate import BusinessDate, BusinessPeriod, BusinessRange, BusinessSchedule
>>> BusinessDate.from_date(date(2014, 1, 1)) == BusinessDate(20140101)
True

>>> BusinessDate(20140101) + '1y6m'
20150701

>>> BusinessDate(20140101).adjust_follow()
20140102

>>> BusinessPeriod('1Y')==BusinessPeriod(years=1)
True

>>> BusinessPeriod('1Y')
1Y

>>> BusinessPeriod('1Y').add_businessdays(3)
1Y3B

>>> BusinessPeriod('1Y') + '1y6m'
1Y6M

>>> sd = BusinessDate(20151231)
>>> ed = BusinessDate(20201231)
>>> BusinessRange(sd, ed, '1y', ed)
[20151231, 20161231, 20171231, 20181231, 20191231]

>>> BusinessSchedule(sd, ed, '1y', ed)
[20151231, 20161231, 20171231, 20181231, 20191231, 20201231]

>>> BusinessSchedule(sd, ed, '1y', ed).first_stub_long()
[20151231, 20171231, 20181231, 20191231, 20201231]
