Singapore celebrates 11 national holidays each year. National holidays are governed under the Employment Act of Singapore and enforced by the Ministry of Manpower. The Ministry of Manpower is given the authority to create one time national holidays and to petition the government for new holidays under these laws.

Each major local race and religion have two holidays each in addition to the secular holidays of New Year's Day, Labour Day and National Day. For the Chinese, Chinese New Year (two days) and the Buddhist holiday Vesak Day (one day) are also observed. For the Hindus, the Buddhist holiday of Vesak Day and Deepavali (one day each) are celebrated. For the Malays, the two Islamic holidays of Hari Raya Aidil Fitri (one day on 1 Syawal) and Hari Raya Aidil Adha (one day on 10 Zulhijah) are celebrated. As for the Christians, the two Christian holidays of Good Friday and Christmas Day (25 December) are celebrated.

If any public holiday falls on a Sunday in Singapore, the following day is declared to be a public holiday if it is not itself already a public holiday.
