Adding calendar months or years with relativedelta clips overflow days to the last valid day of the target month, ensuring dates like January 31 advance to February 28 or 29 without raising an error
relativedelta distinguishes relative offsets using plural kwargs from absolute field replacements using singular kwargs and allows combining both in a single operation
Unindexed and nth-instance weekday specifications navigate forward or backward to target weekdays relative to a reference date
Computing relativedelta between two datetimes decomposes the exact elapsed time into normalized calendar units that reconstruct the original date when added
