# holidays
|

# --------
|
||||
# A fast, efficient Python library for generating country, province and state
|
||||
# specific sets of holidays on the fly. It aims to make determining whether a
|
||||
# specific date is a holiday as fast and flexible as possible.

Sinhala Buddhist Uposatha day calculation method is different from Thai LuniSolar
|

and Buddhist (Mahayana) used in East Asia.
|

|

Due to the fact that Poya (Uposatha) days are calculated astronomically
|
||||
based on how close a particular day is closest to full moon at noon, and that
|
||||
an extra month is added every 33 months interval, this is hardcoded for now.
|
||||
|
||||
Adhi month dates are instead hardcoded in Sri Lanka country implementation.
