The 12 August is Her Majesty Queen Sirikit's birthday. This public holiday is celebrated nationwide as Mother's Day ("WAN MAE HENG CHAT" - วันแม่แห่งชาติ). The Queen is considered as the mother of all Thai people.
Every year in August, all buildings are covered up with Royal symbols and portraits of Her Majesty all over the Thai kingdom.
Long Live The Queen.
