How it works
Sleeps = calendar days between today and the big day
“Sleeps” is the number of nights between now and the day itself — the same as the day count, because you go to sleep tonight and wake up one day closer. A paper chain with one link per sleep, torn off each morning, is the classic way to make the countdown visible for small children.
Worked example
From 26 September to 25 December is 90 sleeps — 12 weeks and 6 days.
Frequently asked questions
Does today count?
