Advent calendars

[Furryscoob]

This year I’m working Christmas Day so we’re moving Christmas Day to Boxing Day.
Has anyone seen chocolate advent calendars with 25 days instead of 24?
My 4 & 7 year old need a bit of bribery to do Christmas Day later than everyone else.

Is an extra door on a chocolate advent calendar really going to help though?

Can you not just give them a bar of choc or a small gift if your Xmas eve /real Xmas day ?

Can you not just start a day later? And do it backwards - counting down from 24 days to go, then they're not mixing up advent days and the date!
