The first day of each lunar month shows the month name, and the heading lists the lunar months, animal year and Buddhist Era year for the month.

Reading the Khmer calendar
Each lunar month begins with ១កើត (1 kert) at the new moon. The full moon is ១៥កើត, and the waning half counts again from ១រោច to ១៤រោច or ១៥រោច. On the calendar, the cell for 1 kert shows the name of the new lunar month instead of the day number, so you can see where each month starts.
The lunar months are មិគសិរ, បុស្ស, មាឃ, ផល្គុន, ចេត្រ, ពិសាខ, ជេស្ឋ, អាសាឍ, ស្រាពណ៌, ភទ្របទ, អស្សុជ and កក្ដិក. In a leap-month year អាសាឍ becomes two months, បឋមាសាឍ and ទុតិយាសាឍ.
Main Cambodian festivals by lunar date
Meak Bochea falls on the full moon of មាឃ, Visak Bochea on the full moon of ពិសាខ and the Royal Ploughing Ceremony four days later. Pchum Ben ends on the new moon of ភទ្របទ after fifteen days of Ben, and the Water Festival is held around the full moon of កក្ដិក. Buddhist Lent (វស្សា) runs from 1 roch of អាសាឍ to the full moon of អស្សុជ.

Frequently asked questions
What are the dots on the calendar?
A gold dot marks a Buddhist holy day (ថ្ងៃសីល): 8 and 15 kert, and 8 and the last day of roch. A red dot and red shading mark a public holiday, and a blue dot marks an observance such as a world day or a Chinese festival.
Does the calendar show Khmer New Year and Pchum Ben?
Yes. Khmer New Year, Pchum Ben, the Water Festival, Visak Bochea, Meak Bochea and the Royal Ploughing Ceremony are all calculated for each year and appear on the right days.
Can I see the Khmer calendar for next year?
Yes. Press → to move month by month, or type any year from 1900 to 2100 in the year box.
Why does a lunar month sometimes have 30 days and sometimes 29?
A lunar cycle lasts about 29.5 days, so Khmer months alternate between 29 days (14 roch) and 30 days (15 roch). Leap months and leap days keep the calendar in step with the moon and the seasons.
