From Wikipedia

Cambodian New Year (Khmer: ?????????????????) or Chol Chnam Thmey in the Khmer language, literally "Enter the New Year", is the name of the Cambodian holiday that celebrates the new year. The holiday lasts for three days beginning on New Year's Day, most commonly April 13th but sometimes on the 14th in keeping with the lunar calendar. Khmer living in other countries may change the dates so as to celebrate on the weekend. This time of the year is at the end of the harvesting season. The farmers enjoy the fruits of their harvest and relax before the rainy season begins.

October and November - Water Festival; this festival celebrates the turn of the current of the Tonle Sap river. The Tonle Sap river connects lake Tonle Sap with the Mekong. For most of the time the river flows from lake Tonle Sap into the Mekong. However, during the rainy season from about June to October the Mekong carries a high water level, and in response the Tonle Sap river flows in reverse direction, from the Mekong back into lake Tonle Sap. This causes lake Tonle Sap to swell to more than twice its regular size. At the end of the rainy season, when the water level of the Mekong drops again, the current reverts and the water added to lake Tonle Sap during the rainy season flows back into the Mekong.
