Working days in Singapore in 1980

How working days in Singapore are counted in 1980

The 257 working days shown above are the 366 calendar days of 1980, minus the 104 Saturdays and Sundays, minus the 5 public holidays that land on a weekday. Holidays that fall on a Saturday or Sunday are not subtracted, because they do not remove a day anyone would have worked; in 1980 that applies to 2 of Singapore's public holidays. At a standard eight-hour day, 257 working days works out to roughly 2,056 working hours across the year, before any annual leave is taken.

What counts as a working day in Singapore

The Employment Act sets a 44-hour standard working week with at least one rest day per week, typically Sunday. The standard private-sector week is Monday to Friday with banks operating Monday to Friday. The Interpretation Act section 50 rolls statutory deadlines from a Sunday or public holiday to the next day that is not a Sunday or public holiday; Saturday is treated as a working day for substantive deadlines. Settlement of Singapore dollar transactions runs on the MAS Electronic Payment System (MEPS+), which closes on the eleven gazetted holidays. Singapore observes no separate banking calendar.

Singapore's Holidays Act in the First Schedule lists eleven public holidays, chosen to balance the city-state's Chinese, Malay and Indian communities. New Year's Day, Labour Day and National Day on 9 August are civic; Chinese New Year (two days), Hari Raya Puasa, Hari Raya Haji, Vesak Day, Deepavali, Good Friday and Christmas Day are religious. The lunar and Islamic-calendar dates are gazetted each year by the Ministry of Manpower. Singapore is among the few countries that gives substitute Monday off when a holiday falls on a Sunday under section 4 of the Holidays Act. There is no separate banking holiday list; the Monetary Authority of Singapore observes the same eleven days.

This matters because the working-day total is not spread evenly. Some months in Singapore carry several public holidays while others have none, so the month-by-month table above is the figure to use for payroll runs, billing cycles, SLA windows, and project plans rather than a flat assumption of about 21.4 working days per month. A month with two weekday holidays can have several fewer working days than a clear one, which changes capacity planning and the realistic delivery date for anything scheduled in business days.

To see the individual dates, the day of the week each holiday lands on, and the full official list, open the Singapore holiday calendar for 1980. You can subscribe to those dates as an .ics feed so they appear in your own calendar, or use the working-days-between-two-dates calculator to count business days for a specific date range rather than the whole year.

Working-day figures are computed from the public holiday list for Singapore (source: Nager.Date and the national references above) combined with a Monday-to-Friday business week. Regional holidays and substitute-day rules vary; confirm against the official calendar for legal or payroll use.
