About¶
businessdate¶
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:
