Being a business owner means that you need to have a clear sense of the rhyme and rhythm of business operations as well as the pulse of society. This means taking note of public holidays (which affect not just your customers but also your employees), other observances that are not necessarily public holidays (such as the eve of public holidays), as well as other events.
Here’s a handy calendar of events that includes all the key dates and public holidays in 2025 to note.

Public Holidays
2025 has a total of 4 conventional long weekends, and another 3 potential long weekends if employees apply for 1-day leave. Businesses should keep this in mind when planning employee rosters and schedule client events or customer promotions accordingly.
1 January 2025 – Wednesday – New Year’s Day
29 & 30 January 2025 – Wednesday & Thursday – Chinese New Year [Long weekend with 1-day leave]

For eligible employees, working on a public holiday typically means an extra day of pay. If employees are entitled to overtime pay for working beyond normal working hours, or for work done on a rest day, they should also be remunerated accordingly.
Singapore will have another public holiday in 2025 for the general election, which must be held no later than 23 November 2025.

School Holidays
Another period that businesses should take note of, outside of public holidays is the school holidays. Not only will it affect students, but it also affects your employees who are parents, who may want to plan for short holidays during this period as it will not disrupt their children’s school schedules.
15 March to 23 March 2025 – March School Holidays
31 May to 29 June 2025 – June School Holidays
7 June 2025 – Saturday – Hari Raya Haji (Monday, 9 June 2025, will be a school holiday) [Long weekend]
9 August 2025 – Saturday – National Day (Monday, 11 August 2025, will be a school holiday) [Long weekend]
06 July 2025 – Sunday – Youth Day (Monday, 7 July 2025, will be a school holiday) [Long weekend]
05 September 2025 – Friday – Teachers’ Day [Long weekend]
06 September to 14 September 2025 – September School Holidays
3 October 2025 – Friday – Children’s Day (for primary schools only) [Long weekend]
22 November to 31 December 2025 – December School Holidays (for primary and secondary schools only)
This year, two public holidays will fall on a Saturday. This means that most employees will get an off-in-lieu rather than a mandated day off. However, schools will close on the Monday, giving parents an opportunity to plan a short getaway as well as a potential scheduling issue if no one is home to take care of their kids.
Another period that businesses should take note of, outside of public holidays is the school holidays. Not only will it affect students, but it also affects your employees who are parents, as well as general customer traffic.
