Singapore Business Day Calculator

The calculator counts Monday to Friday and leaves out the 11 public holidays the Ministry of Manpower lists. When one falls on a Sunday, section 4(2) of the Holidays Act 1998 makes the next day that is not itself a public holiday a public holiday too, and the calculator leaves that day out as well. Employees covered by the Employment Act are entitled to the 11 as paid public holidays; for anyone else, the employment contract decides. A holiday on a Saturday adds no public holiday under the Act, although MOM says an employee whose Saturday is a non-working day should get either a day off or salary in lieu; the calculator keeps the following Monday as a business day.

The dates move. In the data for 2024 to 2029, 4 of the 11 keep one calendar date (New Year's Day, Labour Day, National Day and Christmas Day). The others fall on a different date in every one of those years: Chinese New Year, Good Friday, Hari Raya Puasa, Vesak Day, Hari Raya Haji and Deepavali. MOM publishes the dates one year in advance, by the third quarter of the year before. The Monetary Authority of Singapore's disclosure for MEPS+, its real-time gross settlement system, dated 9 December 2024, says the system "operates on weekdays (excluding public holidays) from 0900 hours to 1900 hours"; the disclosure does not list the holidays.

The 11 gazetted public holidays:

• New Year's Day (1 January)
• Chinese New Year Day 1
• Chinese New Year Day 2
• Good Friday
• Hari Raya Puasa
• Labour Day (1 May)
• Vesak Day
• Hari Raya Haji
• National Day (9 August)
• Deepavali
• Christmas Day (25 December)

When two public holidays fall on the same day, section 5(2) of the Holidays Act lets the President declare an additional public holiday, on any day of that year, by notification in the Gazette; it is not automatic. For 2028 and 2029 the dates of Chinese New Year, Hari Raya Puasa, Vesak Day, Hari Raya Haji and Deepavali are calculated and marked (approximate) until MOM publishes them. Hari Raya Puasa has no row in the 2029 data until MOM publishes that year. How we determine holidays →

MAS Notice 610 (last revised on 16 May 2024) sets a deadline in days and looks at business days only at its end. Under paragraph 5, subject to paragraphs 6 and 7, a bank furnishes the forms that are due monthly "no later than 14 days after the last day of each month"; paragraph 6 gives one monthly form, Appendix B1 Annex 1, 10 days. Under paragraph 8, if the day on which the information is due "is not a Business day, the bank may furnish the information on the next Business day". The Notice's own definitions do not include "Business day". To test a date in this calculator, enter it as both the start and the end date under Between Dates and tick both include boxes: a result of 1 business day means the calculator counts that date, and 0 means it is a Saturday, a Sunday or a holiday in the data.

The Ministry of Manpower's page says that an employee covered by the Employment Act is "entitled to 11 paid public holidays in a year", and that an employee who works on a public holiday should by default be paid an additional day's pay or, by mutual agreement, can get a public holiday in lieu. For a team in Singapore that works to a client's calendar in another country, the calculator loads one country's holidays at a time under Holiday Calendar. To count against both, keep Singapore selected and type the client's holidays under Advanced options as custom dates to exclude, one per line.
