Use Working Days Calculator (Indonesia)

Working day rules

Collective leave is mandatory for civil servants (ASN); for private-sector employees it is optional and reduces annual leave entitlement. Turn it off if your company doesn’t follow it.

Enter both dates to count the working days.

National holiday and collective leave data: 2026 and 2027, according to the SKB 3 Menteri (checked 31 October 2026). Religious holiday dates can shift if the government changes them.

How to use Working Days Calculator (Indonesia)

  1. Choose Count working days or Add / subtract working days.

  2. Enter the dates, then set the work week (5 or 6 days), whether collective leave counts as a holiday, and any extra holidays.

  3. Read the number of working days or the resulting date, along with the list of holidays that fall on working days.

What counts as a day off

Non-working days are weekends (Saturday–Sunday, or only Sunday on a 6-day work week), national holidays and collective leave. Collective leave is mandatory for civil servants (ASN), but optional for private-sector employees and reduces their annual leave entitlement, so this tool provides a switch to include it or not. A national holiday that falls on a weekend does not reduce working days twice.

The holiday data covers 2026 (SKB Nos. 1497, 2 and 5 of 2025) and 2027 (SKB Nos. 1205, 3 and 2 of 2026). Other years are not available yet: the tool only skips weekends and shows a warning. The next year’s SKB is usually issued between September and December, and we will update the data.

A note on religious holiday dates

The dates of Eid al-Fitr, Eid al-Adha and the start of Ramadan are set by the Minister of Religious Affairs in a separate decision, so they can shift from what the SKB lists. Companies can also set their own holidays through employment agreements or company regulations; add them in the extra holidays field.

Questions about Working Days Calculator (Indonesia)

How many working days are there in a year in Indonesia?

It depends on the calendar. On a Monday-to-Friday work week, a normal year has about 261 Monday–Friday days, minus the national holidays and collective leave that fall on working days. Use this tool for the exact number in any date range.

Does collective leave reduce working days?

For civil servants, yes. For private-sector employees, collective leave is optional and, if taken, reduces annual leave entitlement. Turn the collective leave option off if your company doesn’t follow it.

What if a national holiday falls on a Saturday or Sunday?

That day is already not a working day, so it does not reduce the count again. This tool does not create a substitute day unless you add it as an extra holiday.

Is the start date counted?

You decide. By default both dates are counted; untick the box if counting starts the day after the start date.

Is my data sent to a server?

No. The calculation runs in your browser and the holiday list is embedded in the page.
