Enter a target date and find out exactly how many days until that date arrives. Set your start date (defaults to today) and your end date, then see the days remaining, broken down into weeks, months, and years too. Toggle whether to include the end date in the count for precise results.

The calculator subtracts your start date from your end date to produce the total number of days remaining. It counts every calendar day between the two dates, and if you check 'Include end date', one extra day is added to the total.
By default, the start date is automatically set to today's local date based on your device's clock. You can change it to any date you like if you want to calculate days from a different point in time.
When this option is checked, the end date itself is counted as a full day. For example, if today is January 1 and your target is January 3, the result without including the end date is 2 days, but with it included the result is 3 days.
This calculator is designed for future dates. If you enter an end date that is before your start date, the result will show a negative number of days, indicating the date has already passed.
The calculator loops through every day in the range and checks whether it falls on a Monday through Friday (weekday) or Saturday/Sunday (weekend). This gives you a precise count of working days versus rest days in your countdown.
The years remaining figure is calculated by dividing the total number of days by 365.25, which accounts for leap years on average. It is a decimal approximation rather than a count of calendar years.
Absolutely. Simply set the end date to any upcoming event — a birthday, wedding, holiday, exam, or deadline — and the calculator will tell you exactly how many days, weeks, and months you have left.
There is no hard limit built into this calculator. You can calculate days until dates many years or even decades in the future, though results beyond a few years are most useful as rough planning estimates.
