One date calculator, three ways to count
Days between, workdays, and countdown — one tool, three modes that answer "how many days are there between two dates" at a glance. Open the page and start; you can also install it to your phone's home screen.
What each mode solves
-
01
Days Between
Pick a start and end date to see the gap in days right away, with an inclusive count alongside. The most direct way to count anniversaries or contract days.
-
02
Workdays
Counts working days only by excluding weekends, with a breakdown of total and weekend days. Use it to plan project timelines or estimate delivery dates.
-
03
Countdown
Pick a single target date to see how many days are left until today; once the date has passed, it shows how many days ago. A favorite for anyone watching a deadline.
When you'll reach for it
Counting leave days, working backwards from a contract expiry, scheduling a project in working days, counting down to an anniversary — these are all "distance between two dates" problems. The date calculator gathers them into one tool, so you never have to count on your fingers or pull formulas in a spreadsheet again.
How to read the result
After it calculates, that large monospace number is the answer, and the unit beneath it (days / workdays / days left) tells you what it means. The colored line under the number changes with the mode: blue for days between, amber for workdays, green for an upcoming countdown, slate for one that has passed — so you can tell which result you're looking at instantly.
