How to use this calculator
- 1
Set the start date (e.g., today or the project start date).
- 2
Set the end date (e.g., a deadline).
- 3
Check that the order does not matter: an end date before the start date is swapped automatically.
- 4
Read the working-day count (Mon–Fri), the weekend-day count and the total calendar days, both end dates included.
- 5
Subtract any public holidays or leave that fall on weekdays in the range, because the tool has no holiday data.
Frequently asked questions
Are the start and end dates both counted?
Yes. Each date is included if it falls on Monday to Friday, and the calendar-day figure includes both ends as well. Monday November 2 to Friday November 6, 2026 shows 5 working days, 0 weekend days and 5 calendar days.
Does it exclude public holidays?
No. Only Saturdays and Sundays are removed, and there is no holiday list for any country. Subtract holidays that fall on weekdays yourself, for example from the 39 weekdays between November 3 and December 25, 2026 if your own calendar has days off in that period.
What if my weekend is Friday and Saturday?
The tool always treats Saturday and Sunday as the weekend. For a different working week it will overcount, and you would need to adjust manually.
Does the order of the dates matter?
No. If the end date is earlier, the two dates are swapped internally, so December 31 back to November 3, 2026 returns the same 43 working days as the forward direction.
How many working days are in a year?
It depends on the weekday of January 1 and on leap years. Counting January 1 to December 31, 2026 gives 261 working days and 104 weekend days out of 365, before any public holidays. Another year can give 260 or 262.
What does the weekend figure measure?
Saturdays and Sundays within the range, both ends included. A range that is only Saturday and Sunday (November 7 to 8, 2026) shows 0 working days and 2 weekend days; one that runs Monday to the following Monday shows 6 working days and 2 weekend days across 8 calendar days.
How is this different from the business days calculator?
This one counts how many weekdays lie between two known dates. The business days calculator starts from one date and finds the date that is a given number of weekdays away. Neither knows about public holidays.

Counting weekdays by hand and why it goes wrong
A full week always contains five working days, so a long range is mostly arithmetic, but the partial weeks at either end are where errors creep in. Whether the first and last day are included, and whether either falls on a weekend, changes the answer by one or two days. The calculator walks the range day by day and counts every Monday to Friday, with both endpoints in play. A useful sanity check is that any run of 7 consecutive calendar days contains exactly five weekdays, so a range of 14 days has 10 and the remainder is whatever the leftover days add.
Worked examples
Each row was run in the calculator with the dates shown. The two rows that cross a month end and a leap day check that the walk through the range does not skip or double-count February 29, 2024: a week from Monday February 26 to Monday March 4 still holds six weekdays, as the 2024 total of 262 working days across 366 calendar days also shows.
| From | To | Working days | Weekend days | Calendar days |

| 2026-11-02 (Mon) | 2026-11-09 (Mon) | 6 | 2 | 8 |
| 2026-11-07 (Sat) | 2026-11-08 (Sun) | 0 | 2 | 2 |
| 2026-11-03 (Tue) | 2026-12-25 (Fri) | 39 | 14 | 53 |
| 2026-11-03 (Tue) | 2026-12-31 (Thu) | 43 | 16 | 59 |
| 2026-01-30 (Fri) | 2026-02-02 (Mon) | 2 | 2 | 4 |
| 2024-02-26 (Mon) | 2024-03-04 (Mon) | 6 | 2 | 8 |
| 2024-01-01 | 2024-12-31 | 262 | 104 | 366 |
| 2026-01-01 | 2026-12-31 | 261 | 104 | 365 |
Inclusive counting and its consequences
Because both end dates are counted, Monday to the next Monday contains six working days, not five. This matters for project plans: if a task starts Monday and must finish the following Monday, you have six working days available, but only five working days have elapsed. If you want elapsed days rather than days on the calendar, subtract one when both ends are weekdays.
Subtracting holidays
The result is a ceiling, not a final figure. For an invoice due 39 working days from November 3, 2026 to December 25, subtract any local public holidays that land on weekdays in that window, since the tool has no holiday data. Do the same for company shutdowns and your own leave. For a team, it is often easiest to quote the weekday count here and then list the exceptions beside it, so the reader can see which days were removed.
A fixed Saturday–Sunday weekend and single days
The weekend is always Saturday and Sunday. A single day counts too: a Tuesday chosen as both start and end gives 1 working day, 0 weekend days and 1 calendar day, while a Saturday gives 0 working days and 1 weekend day. An empty date field returns a dash instead of a count. Workplaces that rest on Friday and Saturday, or run six-day weeks, will get a different true count. Entering the dates in reverse order does no harm, since the tool swaps them for you. The page opens with an end date of 2025-12-31 and a start date taken from your device clock, so on first load the range often runs backward and is swapped; set both fields before reading the figures.
