Another useful option you can use is --date="string" (or -d "string") option to display a date from x days ago or in x days (or x weeks, months, years et cetera). See
the examples below.
date --date="3 months 1 day ago"
Will print the date 3 months and 1 day ago from the current date. Note that --date="x month x day ago" and -d "x month x day ago" are equivalent.
The above command will print the date 3 days forward in time from now.
