Khmer | Calendar 1987
In 1987, Cambodia was slowly emerging from a decade of turmoil following the fall of the Khmer Rouge regime (1979) and the subsequent Vietnamese occupation. While politics dominated headlines, the daily lives of Cambodians—both inside the country and in diaspora communities in France, the US, and Australia—continued to be guided by an ancient, sophisticated lunisolar system: the Khmer calendar.
The year 1987 in the Gregorian system corresponds primarily to Buddhist Era (BE) 2530 (from January 1 to April 13, 1987) and BE 2531 (from April 14 to December 31, 1987). For the Khmer, the most significant turning point was not January 1, but Chaul Chnam Thmey—the Khmer New Year—which fell on April 13, 14, and 15, 1987 (BE 2531).

The most sacred Buddhist holiday—marking the birth, enlightenment, and parinirvana (death) of the Buddha. It falls on the full moon of Visak (April–May). In 1987, the day was observed with candlelit processions around pagodas. In Cambodia, the government allowed limited religious gatherings, though under close monitoring. In the West, the day became a powerful symbol of cultural survival.
The Khmer calendar relies on complex astronomical formulas for determining the precise moment of Moha Songkran (sun entering Aries). Slight variations exist between the calendar used in Cambodia (based on the Chulasakarat era + 638) and that used by Thai Khmer communities. Additionally, in 1987, many original calendar manuscripts were destroyed under the Khmer Rouge (1975–79). Survivors reconstructed the calendar from memory and from surviving monks who had fled to refugee camps. Therefore, some diaspora communities observed holidays one day off from those inside Cambodia.
Nevertheless, for the vast majority of Cambodians in 1987—whether in a rice field in Kampong Cham, a garment factory in Phnom Penh, a resettlement camp in Thailand, or a kitchen in Seattle—the Khmer calendar was not a relic of the past but a living, breathing structure that gave order to a world still trying to heal.

Title: An Indispensable Digital Bridge to Cambodia’s Cultural and Religious Heart
Rating: 4.6/5 (Highly Recommended for the Cambodian diaspora and historians)
Review:
As someone who relies on traditional lunar dates for religious observances (Kathen, Pchum Ben) and personal milestones, finding a reliable digital reference for past years is surprisingly difficult. The Khmer Calendar 1987 app/resource is a hidden gem that fills this niche remarkably well.
The Good: Accuracy and Context This is not just a grid of numbers. The standout feature is the meticulous alignment of the Chhankitek lunar system with the 1987 Gregorian year. The Buddhist Lent days (Vossa), the exact dates of the full moon and new moon, and the naming of lunar months (M reconciliationi, Phalkun, etc.) are presented with a clarity that rivals printed, temple-distributed wall calendars. For anyone researching events from that era or trying to retroactively confirm a birth date in a Cambodian family record, this is pure gold. The inclusion of minor solar and lunar eclipses (visible over Southeast Asia) was a surprising and welcome touch.
The User Experience (App/PDF) The interface is refreshingly no-frills. On the version I use, you can toggle between Khmer and English script, which is vital for elders who read the traditional numerals and second-generation Cambodians who do not. The layout respects the traditional week start (Sunday, marked in red) and clearly distinguishes between Knyei (civil) and Thngai Sdach (royal/religious) reference points.
One Note of Caution Some users might find the design utilitarian rather than beautiful, and I did notice a minor spacing issue in the month of November 1987 (the Khmer text for the lunar date overlapped slightly on one line). However, this does not affect the core utility of the calendar, which is first and foremost a reference tool.
Final Verdict Whether you are a history student writing a paper on the final years of the People's Republic of Kampuchea, a monk needing to backtrack a religious holiday, or a Cambodian family wanting to check the exact lunar date of a loved one’s birth, this calendar is essential.
It preserves a piece of the Khmer temporal fabric that is often lost in standard digital calendars (Google Calendar, iCal). Highly recommended.
