Calculator
Pick a date and see how many days are left until it — or how many days have gone by since it passed. Updates live, no page reload needed.
Works both ways — pick a date in the future for a countdown, or in the past to see days elapsed.
The calculator compares your chosen date to today, at midnight in your local calendar, and counts the whole days between them. If the date is still ahead, you'll see "days until." If it's already passed, you'll see "days since" instead — same math, just framed the other direction. Today itself always reads as zero.
If you need the gap between two specific dates instead of one date and today, the Date Difference Calculator does that. If you only care about working days — for a deadline or a project plan — use the Business Days Calculator instead.
