Frequently asked questions
Does the countdown include the target day itself?
The days figure is the difference between today and the target date. If the event is today, it shows 0 days. For an inclusive “how many sleeps” count, add 1 to the result.
Why do the weeks and months numbers not always add up neatly?
Weeks are computed from the exact number of days (days ÷ 7), while months are calendar months, which vary in length. A 45-day countdown is about 6 weeks but lands roughly 1 month and 15 days on the calendar.
What happens if I pick a date in the past?
The calculator tells you the date has already passed and shows how many days ago it was, so it also works as a quick “how long since” tool.
