So here are the basics of the Thai Lunar Calendar 3-year types for calendar intercalation: - Pakatimat (Normal Year): consist of 12 months, has 354 days. - Athikawan (Extra-Day Year): add a day to the 7th month of the year, has 355 days for the synodic month correction. - Athikamat (Extra-Month Year): we have the 8th month twice, has 384 days for the sidereal year correction. Each month either has 30 (Even months) or 29 (Odd months) - The waxing phase has 15 days until Full Moon and waning phase 14 (Odd Months)/15 (Even Months/ Month 7 of Athikawan years) days for the New Moon. - The second "Month 8" for Athikamat years is called "Month 8.8", with all observed holy days delayed from the usual calendar by 1 month. List of public holidays dependent on the Thai Lunar Calendar: - Magha Puja/Makha Bucha/Meak Bochea: 15th Waxing Day (Full Moon) of Month 3 (On Month 4 for Athikamat Years). KHMER_CALENDAR always fall on Month 3. - Vesak/Visakha Bucha/Visaka Bochea: 15th Waxing Day (Full Moon) of Month 6 (On Month 7 for Athikamat Years). KHMER_CALENDAR always fall on Month 6. - Thai Royal Ploughing Ceremony/Raeknakhwan: Based on this, though Court Astrologer picks the auspicious dates, which sadly don't fall into a predictable pattern; see its specific section below. - Cambodian Royal Ploughing Ceremony/Preah Neangkol: 4th Waning Day of Month 6 (On Month 7 for Athikamat Years). This defaults to KHMER_CALENDAR (its sole user). - Asalha Puja/Asarnha Bucha: 15th Waxing Day (Full Moon) of Month 8 (On Month 8/8 for Athikamat Years). KHMER_CALENDAR always fall on Month 8. - Buddhist Lent Day/Wan Khao Phansa: 1st Waning Day of Month 8 (On Month 8/8 for Athikamat Years). KHMER_CALENDAR always fall on Month 8. - Pchum Ben/Prachum Bandar: 15th Waning Day (New Moon) of Month 10. - Loy Krathong/Boun That Louang/Bon Om Touk: 15th Waxing Day (Full Moon) of Month 12. Other Buddhist date on Thai Lunar Calendar: - Buddha's Cremation Day/Atthami Bucha 8th Waning Day of Month 6 (On Month 7 for Athikamat Years). KHMER_CALENDAR always fall on Month 6 - End of Buddhist Lent Day/Ok Phansa: 15th Waxing Day (Full Moon) of Month 11 The following code is based on Ninenik Narkdee's PHP implementation, and we're thankful for his work.
