This lunar month

Phdrabot is the tenth lunar month, falling in August–September at the end of the rainy season. It is the time of Kan Ben, when families take morning food offerings to pagodas before Pchum Ben.

The season in Cambodia

Rainy season (May–September): the monsoon rains arrive and rice planting begins. Rivers rise, fields fill with water, and monks keep the Vassa rains retreat. It is also the season of Kan Ben and Pchum Ben at its end.

Khmer calendar glossary

  • Koeut (waxing) — the first half of the lunar month, days 1 to 15, as the moon gradually grows toward the full moon.

  • Roach (waning) — the second half of the lunar month, as the moon wanes from full to new.

  • Thngai Sil — Buddhist observance days falling on the 8th and 15th of each waxing and waning half.

  • Penh Pornami — the full-moon day (15 Koeut), an important day for merit-making at pagodas.

  • B.E. (Buddhist Era) — counts years from the Buddha's passing, stepping at Khmer New Year.

  • Sak — a ten-year cycle count used alongside the animal year, such as Atthasak (eighth).

  • Vassa — the rainy-season retreat when monks remain at their monasteries for three months.

What is B.E. (Buddhist Era)?

B.E. counts years since the Buddha's passing. The year steps at Khmer New Year, so B.E. runs about 544 years ahead of the Gregorian year.

Learn more
What is Thngai Sil?

Thngai Sil (holy days) fall on the 8th and 15th of each lunar half. Many Buddhists keep the precepts, listen to sermons, and make offerings at pagodas on these days.

Learn more
What is the difference between Kan Ben and Pchum Ben?

Kan Ben is the fourteen days before Pchum Ben when families bring morning offerings to pagodas each day. Pchum Ben is the culminating day when people visit pagodas to dedicate merit to their ancestors.

Learn more
How is the Khmer lunar month counted?

The Khmer lunar month follows the moon: 15 waxing days and 14–15 waning days, making months of 29 or 30 days. Leap years add an extra month to stay in step with the solar year.

Learn more
Why is B.E. about 544 years ahead of the Gregorian year?

The Buddhist Era counts from the Buddha's passing, which occurred roughly 544 years before the start of the Common Era, so B.E. always runs about 544 years ahead.
