Find out exactly how many days are left until any date — or how many have passed since.
How the Countdown Is Calculated
This tool calculates the exact number of calendar days between today's date and your chosen target date, then converts that figure into weeks, approximate months, business days (Monday through Friday only), and total hours.
Days = (target date − today's date), in whole calendar days
Business days = calendar days, excluding Saturdays & Sundays
Future vs. Past Dates
Choose a date in the future to get a countdown ("32 days remaining"), or a date in the past to see elapsed time ("18 days since"). Leap years are automatically accounted for since the calculation is based on actual calendar dates, not a fixed 365-day assumption.
Common Uses
- Counting down to a wedding, birthday, holiday, or vacation
- Tracking a project deadline or exam date in business days
- Calculating how many days pregnant someone is, or days until a due date
- Figuring out how many days have passed since a milestone or anniversary
❓ Frequently Asked Questions
Does the countdown include today as one of the days? ▼
The calculation measures the difference between today's calendar date and the target date, so today itself isn't counted as a full day remaining — the count reflects whole days between now and the target.
How is "business days" calculated? ▼
Business days count only Monday through Friday, excluding Saturdays and Sundays. It does not automatically exclude public holidays, since those vary by country and region.
Can I use this for a date in the past? ▼
Yes — enter any past date and the tool will show how many days, weeks, and months have elapsed since that date rather than a countdown.
Does this account for leap years? ▼
Yes, the calculation uses actual calendar dates (via JavaScript's Date object), which automatically accounts for leap years and varying month lengths — there's no fixed 365-day assumption involved.
What is this tool commonly used for? ▼
Popular uses include counting down to weddings, birthdays, holidays, and vacations, as well as tracking project deadlines, exam dates, and due dates in business or personal planning.
