getdate {bizdays} | R Documentation |
Imagine you have one date and want the first or last day of this date's month.
For example, you have the date 2018-02-01 and want the last day of its month.
You have to check whether or not its year is a leap year, and this sounds a
tough task.

helps with returning specific dates according to a reference
than can be another date, a month or an year.
