Make it law that advent calenders have 25 days and not 24

Background

The price of chocolate in the UK has shot up recently, but what has really topped it off is i have spent £20 for 4 advent calenders that all have 24 days. Chocolate companys are charging more but taking a day off, make it law that all calenders must be sold with door 25 on. And bigger than the rest

Additional details

I would like the goverment to put a law un place that all advent calenders must be sold with the number 25 door on them And that sweet treat behind number 25 must be bigger than all the others. And there must be no price increas on the cost of the calender
