In climatology, data is often reported in multi-day formats, such
as dekads (a 10 day definition) or pentads (a 5 day definition).
kalendar is a Python package with datetime.date extensions
for dekadal and pentadal calendar definitions that make
it easier to work with such climate data.
Install and update using pip:
pip install kalendarThe dekadal and pentadal classes are simple subclasses with convenient
constructors for creating the class from datetime objects (and
inherited constructors from datetime.date), methods for addition
and subtraction, and converting back to datetime.date objects.
from kalendar import Dekad, Pentad
d = Dekad(2022, 1)
p = Pentad(2013, 51)See the documentation for full examples.
