You need calendar-day totals for planning, a trip, an event, a deadline, or a rough weekday/weekend split.
Days Between Dates Calculator
Count the exact days between two dates, compare elapsed and inclusive totals, and see whole weeks, Monday–Friday dates, and weekend dates.
Choose the start date and end date.
Your selected dates are calculated locally in your browser and are not uploaded to a server.
Count exact days until or since a deadline
The Monday–Friday and weekend counts include both dates. Public holidays and workplace calendars are not applied.
The end date is after the start date.
Count the exact days between any two dates
Select a start and end date to see the elapsed difference, the count with both dates included, whole weeks plus remaining days, and the Monday–Friday and weekend split.
The Monday–Friday result is not a holiday-aware business-day count. Public holidays, work schedules, time zones, and legal day-count rules are not applied.
Age Calculator: Calculate age in years, months, and days from a birth date to a target date.

How to Read the Result
Date calculations can mean slightly different things depending on the task. This page shows both the gap between dates and the inclusive count so you can choose the number that fits your use case.
| Result | What it means | Good for |
|---|---|---|
| Days between | The difference from one date to the other | Deadlines, elapsed time, and waiting periods |
| Including both dates | Counts the start date and end date as included days | Trip length, event duration, and schedules |
| Whole weeks + days | Breaks elapsed days into complete weeks and a remainder | Readable planning intervals |
| Monday–Friday dates | Counts weekdays in the inclusive range | Rough scheduling, not holiday-aware business days |
| Weekend dates | Counts Saturdays and Sundays in the inclusive range | Trip and event planning |
Elapsed Days Versus Inclusive Calendar Days
From June 1 to June 10, the elapsed difference is 9 days because nine midnights are crossed. If an event includes both June 1 and June 10, the inclusive calendar count is 10 days.
A hotel stay commonly uses elapsed nights, while a schedule, leave period, or multi-day event may use an inclusive count. Always match the result to the rule of the task.
| Example | Use this result | Answer |
|---|---|---|
| June 1 to June 10 as elapsed time | Days between | 9 days |
| June 1 through June 10, both included | Inclusive calendar days | 10 days |
| Monday–Friday count | Included weekdays | Still check public holidays |
FAQ
Does it include the start and end dates?
The tool shows both the plain day difference and an inclusive count that includes both dates.
Can I count backward or swap the dates?
Yes. The totals use the absolute difference, and the swap button reverses the start and end dates instantly.
Why is the elapsed count one day lower than the inclusive count?
Elapsed days count the midnights crossed. Inclusive days also count both calendar endpoints, so the inclusive result is one higher for valid dates.
Does the Monday–Friday count equal business days?
Not necessarily. It counts weekdays in the inclusive range but does not remove public holidays or apply a workplace calendar.
Are my dates uploaded?
No. The calculation runs in your browser.
