By default it will use the current day. The first day of the month has value 1.
Add an anchor month for the relative dates such as a day after tomorrow (Default: -1
).
Add an anchor month for the relative dates such as a day after tomorrow (Default: -1
).
By default it will use the current month. Month values start from 1
, so 1
stands for January.
Add an anchor year for the relative dates such as a day after tomorrow (Default: -1
).

If it is not set, the by default it will use the current year. Example: 2021
