Days Between Dates

Pick any two dates and instantly see exactly how many days sit between them, with a weeks, months and years breakdown. Perfect for deadlines, anniversaries, project timelines and “how long until…” questions.

Differences

Business Days Calculator

Count the real working days between two dates — weekends stripped out, and US federal holidays too if you want. Built for payroll windows, delivery promises, contracts and leave planning.

Differences

Time Duration Calculator

Measure the exact gap between two moments — down to the minute. Handy for shift lengths, travel time, event durations and billing hours.

Differences

Days From Today

Answer “what date is 90 days from now?” — or work backwards from any date to today. Great for follow-ups, warranty ends, trial expiries and 30/60/90-day plans.

Countdowns

Countdown Maker

Name your big moment — a wedding, launch day, vacation or birthday — and get a live ticking countdown card that updates every second. Made for anyone counting down to something good.

Countdowns

Holiday Countdown Board

Every US federal holiday, counted down live and sorted with the nearest one first. For planning time off, travel and long weekends — no calendar flipping required.

Countdowns

Year Progress

See exactly where you stand in the year right now — how much has passed, how much is left, and which week you are in. A favorite for goal-setters, planners and New Year resolution keepers.

Explorers

Day of the Week Finder

Drop in any date — a birthday, a historical moment, a future plan — and learn its weekday, its day-of-year, ISO week number and quarter. Curiosity welcome; historians and trivia fans love this one.

Explorers

Leap Year & Month Explorer

Check whether any year is a leap year, see the simple rule behind it, and find out how many days any month has in that year. Students, teachers and February-29 babies start here.

10,000 Days Milestones

Enter a birth date to find out exactly how many days old you are today — and the calendar dates of your 1,000 to 25,000-day milestones. A fun excuse to celebrate a birthday that is not on your birthday.
