Her Majesty Norodom Monineath Sihanouk is the mother of King Norodom Sihamoni of Cambodia. The birthday of the Queen Mother is a national holiday in Cambodia, with government offices, schools, and many businesses closed. The holiday is a relatively quiet one, with no lavish festivities normally planned. This is in contrast to the three-day celebration of King Sihanouk‘s Birthday, the former king and late husband of Queen Sihanouk. Discuss
