How the weeks until Christmas are calculated
The calculator counts the calendar days from your start date to December 25. It then divides by 7. The whole number is the weeks, and the remainder is the extra days. If your start date is after December 25, it counts to Christmas of the following year.
Weeks until Christmas
Total days = Christmas date − start date
Weeks = total days ÷ 7, rounded down
Extra days = total days − (weeks × 7)
Sleeps to go is the same as the days left, because there is one night before each day. Weekends are counted by Saturdays, and weekdays are Monday to Friday.
