I ran a bedtime digital detox challenge that ended on the 19th for programming but ended on the 18th for clients. The purpose of the challenge is to not use your phone before bed, needing to mark off yesterday's habit the following day. Many clients who marked off their final day (the 18th) on the 19th did not receive the point for it, even though the last day set for the challenge is the 19th. Whatever day the program challenge is set to should allow for you to still earn points. I am presuming I should have had it set to the 20th as the last day instead?
