Custom date period

[cavedweller]

Is it possible to only have the past 30 days available on the calander so say from current day less 30 days

So it wont be able to go forward past that date or backward past the other date

Reason for this, say you have data that will be available for 30 days once 30 days have passed then the data is deleted, it makes it easier for users to understand how much longer they have access to that specific data

any guidance would be greatly appreciated
