Public holidays in Bangladesh

Bangladesh has numerous public holidays, including national memorial, religious and secular holidays of Bengali origin. The Bengali traditional calendar, known as Baṅgābda is the national and official calendar in Bangladesh. The holidays are celebrated according to Bengali, Islamic or Gregorian calendars for religious and civil purposes, respectively. Religious festivals like Eid are celebrated according to the Islamic calendar whereas other national holidays are celebrated according to the Bengali and Gregorian calendar. While the Islamic calendar is based on the movement of the moon, it loses synchronization with the seasons, through seasonal drift. Therefore, some public holidays are subject to change every year based on the lunar calendar.

There are fifteen public holidays in Bangladesh. Muslims and non-Muslims have four religious holidays each in addition to the seven secular national holidays. For the Muslims, nine major Islamic holidays: Ashura, Mawlid, Isra' and Mi'raj, Shab-e-Barat, first day of Ramadan, Revelation of the Quran, Laylat al-Qadr, Eid ul-Fitr and Eid ul-Adha are observed. For the Hindus: Holi, Krishna Janmashtami, Durga Puja, Diwali and Raksha Bandhan are celebrated. As for the Christians: New Year, Good Friday, Easter Saturday, Easter Sunday, Halloween, Christmas Eve, Christmas, Boxing Day, St. Patrick's Day and New Year's Eve are celebrated. Buddhists: Vesak and Chinese New Year are celebrated.
