A countdown calculator measures the time left until an event — a holiday, deadline, wedding or launch — broken down into years, months, weeks and days so you can plan and build anticipation.
The calendar gap is calculated from the two dates, borrowing across month boundaries so it stays accurate over uneven months and leap years. Weeks and days are the total elapsed time divided by 7 and counted inclusively.
It measures elapsed time between the dates, so neither day is counted as a full extra day. Add one if you need inclusive counting.
The calculator notes that the date has passed and shows how long ago it was, so it doubles as a 'time since' counter.
