  The calendar fell out of official status in several mainland Southeast Asian kingdoms (except Burma) in the second half of the 19th century with the arrival of European colonialism. The Gregorian calendar replaced the Burmese calendar in Cambodia in 1863 and Laos in 1889. In 1889, the only remaining independent kingdom in Southeast Asia, Siam, also replaced the Burmese calendar and switched to the Gregorian calendar as the official civil calendar and the Ratanakosin Era (with 1782 CE as Year 1) as the traditional lunisolar calendar.
  
  In Burma (Myanmar), the Burmese calendar has not been replaced, but used alongside the Gregorian calendar after the fall of the Burmese kingdom. Thailand has moved on to its own version of the Buddhist calendar since 1941, although the Chulasakarat era dates remain the most commonly used and preferred form of entry in academic use for historical studies. The Chittagong Magi-San calendar, identical to the Arakanese calendar, is still used by Chakma and Marma ethnic minorities of Bangladesh.
  
  Today, the Calendar Advisory Board within the Ministry of Religious Affairs and Culture of Myanmar is tasked with keeping the lunisolar calendar in line with the solar year.
