Hi @Admin_Department1,
I would make a formula that shows me the number of days it has been from Check-In to Today
DATETIME_DIFF(TODAY(), {Check In Date}, 'days')
Then create the three views, 30 day, 60 day, 90 day.
Set filter for 30day view to:

Do the same with modified numbers for the remaining two views.
