Parameters
----------
name : str
Name of the holiday , defaults to class name
offset : array of pandas.tseries.offsets or
class from pandas.tseries.offsets
computes offset from date
observance: function
computes when holiday is given a pandas Timestamp
days_of_week:
provide a tuple of days e.g (0,1,2,3,) for Monday Through Thursday
Monday=0,..,Sunday=6
Examples
--------
>>> from pandas.tseries.holiday import Holiday, nearest_workday
>>> from dateutil.relativedelta import MO
>>> USMemorialDay = Holiday(
... "Memorial Day", month=5, day=31, offset=pd.DateOffset(weekday=MO(-1))
... )
>>> USMemorialDay
Holiday: Memorial Day (month=5, day=31, offset=<DateOffset: weekday=MO(-1)>)
>>> USLaborDay = Holiday(
... "Labor Day", month=9, day=1, offset=pd.DateOffset(weekday=MO(1))
... )
>>> USLaborDay
Holiday: Labor Day (month=9, day=1, offset=<DateOffset: weekday=MO(+1)>)
>>> July3rd = Holiday("July 3rd", month=7, day=3)
>>> July3rd
Holiday: July 3rd (month=7, day=3, )
>>> NewYears = Holiday(
... "New Years Day", month=1, day=1, observance=nearest_workday
... )
>>> NewYears # doctest: +SKIP
Holiday: New Years Day (
month=1, day=1, observance=<function nearest_workday at 0x66545e9bc440>
)
>>> July3rd = Holiday("July 3rd", month=7, day=3, days_of_week=(0, 1, 2, 3))
>>> July3rd
