Business Day Calendar
Last reviewed: October 14, 2026
A business day calendar highlights weekends and public holidays so you can count the working days across a range of dates at a glance.
Choose a country, click a start day, then click an end day. The span between them fills with an accent tint, weekends and public holidays inside it stay marked, and the counter shows how many business days, weekend days, and holidays the range covers.
| Sun | Mon | Tue | Wed | Thu | Fri | Sat |
|---|---|---|---|---|---|---|
| Sun | Mon | Tue | Wed | Thu | Fri | Sat |
|---|---|---|---|---|---|---|
Click a start day, then an end day, to measure the span.
Pick two days on the calendar to count the business days between them.
How to read the calendar
Every day on the grid is shaded by type. Regular working days sit on the plain background. Weekend days carry the muted secondary shade. Public holidays show an amber tint with the holiday's name; on today's date the cell shows Today in place of the name. Once you click a start day and an end day, the days between them (and both endpoints) take on a blue accent, so a project window, a payment period, or a notice deadline reads as a single block. The two days you clicked get a stronger accent and a ring, and the current date carries its own outline after the page loads.
What the calendar leaves out
A business day is any day that is not a weekend day and not a public holiday. The counter reflects that: it subtracts the weekend days and the public holidays that fall on a day of the country's working week from the calendar-day span, and the remainder is the business-day count. A holiday on a weekend day is counted once, as a weekend day. Public holidays come from the same per-country data the rest of the site uses; each country's holiday pages and the sources register name the source of its dates. Not every date is a published one: some later-year dates are computed ahead of the authority's own list, and the holiday pages tag the ones the data marks as approximate or unconfirmed. The data runs from 2024 to 2029. Outside those years the calendar marks no holidays and counts weekends only, and a notice under the calendar says so. Switch the country and the holidays redraw. Switch to a country with a different weekend and the shaded days move too.
Weekends are not the same everywhere
For most of the 25 countries the calendar uses a Saturday-Sunday weekend. Four are different. For Saudi Arabia, Qatar and Egypt it counts a Sunday-to-Thursday week and shades Friday and Saturday instead, following the government sources the sources register lists for each. For Israel it counts the week of ZAHAV, the Bank of Israel's payment system, Sunday to Friday, and shades only Saturday; a control under the country list switches to the Sunday-to-Thursday week of government ministries on a five-day week, and that choice lasts until the page is reloaded. The UAE federal government has worked Monday to Friday, with Friday a half day, since 1 January 2022, and Saturday and Sunday are its weekend, so the UAE calendar uses the Saturday-Sunday weekend. Because the weekend set drives the shading and the count, picking the right country matters: the same ten-day window can hold a different number of business days in Riyadh than in London.
How the count treats the start and end day
The range is inclusive of both endpoints. When you select Monday the 4th as the start and Friday the 8th as the end, all five days are inside the range, and any of those five that are business days are counted. This matches the Between Dates tool when you tick both "Include start date in count" and "Include end date in count". If you need the exclusive convention instead (counting from the day after the start), the Between Dates calculator lets you toggle each endpoint.
