I think you'll have to cancel the travel day on the 23rd and then activate the pass again with start date on the 22nd.
You can cancel a travel day in My Pass: select the travel day and tap on "Cancel travel day”.
There is no need to activate a travel day a long time in advance. The best is only to activate when you're absolutely certain of the date, because if you change plans and forget to cancel your travel day, then you loose it. A travel day can only be cancelled when it hasn't started yet.

Anyway, Is it ok to just activate the pass on the first day to trave, in this case on the 22nd? Thank you.
