Days Between Dates — With or Without the First Day
Between two dates
Off gives days after; on gives the day count including the day you start on.
Result
Weekdays exclude Saturdays and Sundays only. Both the first and the last day are counted here, so “Count the first day too” does not change this number — which is why it can read higher than the day count. Public holidays are not counted, because they differ by country and change each year.
This counts calendar days. Hours, minutes and time zones are not involved.
Days before or after a date
The dates stay in your browser and are never sent anywhere.
About Days Between Dates
Put in two dates and get the number of days between them, the number of weekdays, and the same gap as years, months and days. The second panel goes the other way: give it a date and a number, and it tells you which day that lands on.
The switch labeled count the first day too is the part worth knowing about. Between the first and the second of a month there is one day of difference, but two days are involved, and both answers are correct for different questions. Deadlines, notice periods and countdowns disagree about which one they mean, and most calculators pick one and say nothing. Here it is a switch, so you can match whichever rule you were given.
Two things this deliberately does not do. It does not count public holidays, because they differ by country and change every year, so weekdays here means Saturdays and Sundays removed and nothing else. And it does not handle hours: it counts calendar days, which is why no time zone can shift the answer.
Nothing is stored and nothing is sent.
How to use it
- Fill in both dates. The order does not matter — a reversed pair gives the same count, never a negative one.
- Decide the first-day question before you trust the number. If a rule says within 30 days of receipt, find out whether the day of receipt counts; that single decision moves the deadline.
- Use the weekday count for anything measured in working days, and read the note under it: holidays are not removed.
- The years-months-days line is for describing a gap in speech, not for arithmetic. Months are different lengths, so those three numbers cannot be added back into a day count.
- For a countdown, use the first panel (between two dates) in reverse: enter the target date as the end and today as the start.
Questions
Is it free, and do I need an account?
Free, and there is no account. The counting happens in your own browser, so there would be nothing to sign in to — the dates never leave the page.
Why do I get a different number from another calculator?
Almost always the first day. One tool counts the starting day and the other does not, and neither says which. Flip the switch here and one of the two numbers will match. The other common cause is a working-days count somewhere that removed public holidays.
Does it subtract public holidays from the weekday count?
No, and that is deliberate rather than unfinished. Holidays differ by country, by region within a country, and from one year to the next, so a built-in list would be wrong for most visitors while looking authoritative. Weekdays here means Saturdays and Sundays removed.
Can I count hours as well?
No. This counts calendar days only. Adding hours would mean choosing a time zone and handling daylight saving, and the result would silently change depending on where the visitor is. Counting whole days avoids that entirely.
How does it handle months of different lengths?
The years-months-days line walks the calendar rather than assuming thirty-day months. When a day overflows the shorter month — one month after 31 January — it is clamped to the last day of that month. Calculators disagree here, so this one states its rule.
Does it work out someone's age?
No, and it never will: there is no birth date field anywhere in the tool. If you want an age, count between two dates yourself and read the years line.
