Sleeps until Christmas: awful answers only

It's that time of year. Some people are counting down sleeps until Christmas day.

I think it would be great if we could help them out with a function or programme of some kind that can help them keep count.

Something that will accept a date and output the number of sleeps until Christmas from that date, or if you don't want to do Christmas, some other date you find important.

One caveat is that the code should, for some reason, get you on Santa's naughty list.

The function should work like so:

sleepsTillChristmas(date) //e.g. 2022-04-15
//output for the example is 264
