A tithi that ends at dusk in Chennai can still be running at dusk a thousand kilometres west, which moves the day. Sunrise and sunset here are computed for the place above.

Sri Lanka calendar, computed for Chennai
What the day is
The full moon of the Sinhala month of Vap, one of the twelve Poya days the island keeps. Every Poya is a day of sil: white is worn to the temple, the eight precepts are taken before a monk, and the day is passed in listening, reciting and meditating rather than in work. This one is kept for the end of the three months of vas and the opening of the Kathina season, in which new robes are offered to the monks who kept the retreat.
- Deity
- Buddha
- Kind
- Observance Days marked, watched or begun, without a fast or a feast of their own.
Significance
Vap closes the three months of vas and opens the season of Kathina, when a robe cloth, offered by the laity, is given to the monks who kept the retreat. The Buddha's descent from the Tavatimsa heaven after teaching his mother is also placed on this full moon, and lamps are lit to welcome him down. The Kathina is one of the gifts most treasured in a household's memory, because it can only be offered once a year, in the month after the retreat, to monks who kept the vas. Families who have pledged dana through the rains bring the three months to a close with it.
How it is kept
The puja as a household does it, in order. Tick each step as it is done.

The hour
Clock times for Friday, 15 October 2027 at Chennai
The day whose sunset the full-moon tithi covers, the evening the moon is seen full, and the second of the two when it covers two sunsets. That reproduces every Poya the government gazetted for 2024, 2025 and 2026. The traditional almanac counts the lunar days from a calculated new moon and can still name another day, so the temple notice is worth reading.
The main rite. The full moon by the local clock. The precepts are taken at the temple in the early morning and kept until dawn the next day; the one meal is finished before noon.
| Instant | Time | What it is |
|---|---|---|
| Sunset | 17:50 | the moment the sun goes down |
| Pradosha kala | 17:50 to 20:14 | the 2 h 24 min after sunset, the evening worship hour |
| Moonrise | 17:33 | the Moon rising at this place, the hour a moonrise vratam is broken |
Sunrise 05:59, sunset 17:50, UTC+5.5. These are the instants the rule is read at, not the temple's own puja times, which every temple prints for itself.
The day itself
| What | When | Note |
|---|---|---|
| Tithi | Shukla Pournami from previous day 18:50 until 19:17 | then Krishna Prathamai until next day 19:14 |
| Nakshatra | Revati until 23:30 | then Ashwini until next day 23:59 |
| Rahu kaal | 10:26 to 11:55 (1 h 29 min) | the eighth of the daylight left alone for a beginning |
| Yamaganda | 14:52 to 16:21 (1 h 29 min) | the eighth ruled by Yama, also avoided |
| Gulika | 07:28 to 08:57 (1 h 29 min) | the eighth of Saturn’s son; what is done in it is said to repeat |
| Abhijit | 11:31 to 12:18 (0 h 47 min) | the midday muhurta, good for most things |
| Moonrise | 17:33 | moonset next day 06:22 |
For Friday, 15 October 2027 at Chennai. A time marked "previous day" or "next day" is on the clock of that day.
The fast
Those who take sil at the temple keep the eight precepts for the day and the night: one meal before midday, nothing solid after it, and no music, ornament or high seat. Others keep the day meatless, and the sale of meat and liquor is closed across the island.
What is avoided
No meat, fish or liquor is sold or served, and nothing is killed; the shops for them close across the island. Those on sil eat nothing solid after noon and leave aside music, dancing, perfume, ornaments and high or luxurious beds, and nobody quarrels or gossips on a Poya.
The name
The same day, in every language that has a word for it
Where the regions differ
Sri Lanka keeps all twelve full moons as public holidays, which no other country does, and an intercalated month adds an Adhi Poya of the same name and gives the year thirteen. The Sinhala month names run one behind the Sanskrit ones, which is why the Kandy Esala Perahera ends on the Nikini Poya.
In other regions
- Sri Lanka (the dates above)
- Sri Lanka opens the Kathina season on this Poya, and temples hold their Kathina peraheras on the weekends after it.
The dates above are the Sri Lanka reckoning, because that is the calendar this key belongs to. Switch the tradition on the calendar page to see how another one dates the same day.
Greeting
What is said to family and friends on the day

Mantras
The prayers said with the day. Each opens with its words and meaning.
- Tisarana (the three refuges)
- Namo Tassa (homage to the Buddha)
- Karaniya Metta Sutta
A name without a link is a long reading, read in full from the family’s own copy or at the place of worship; the library prints the shorter prayers.
Fixing a day for it
The muhurtham rules for a puja held alongside, whose day the family chooses
Vap Poya's own date is set by the rule in "The hour" above, and no muhurtham moves it. For a temple visit around it, whose day the family does choose, the finder below applies these rules.
A temple visit, or the first darshan at a new temple. No weekday is ruled out: Tuesday belongs to Murugan and the Amman, Saturday to Perumal and Sani, so the day usually follows the deity rather than the almanac. Ashtami and Chaturdasi are the two tithis held back for darshan, with the standing exceptions of Sivaratri on Krishna Chaturdasi and Kala Bhairava Ashtami, which are kept on those very days. Rahu kaal, Yamaganda and Gulika kaal are not scored here; the panchangam page prints them for the day you pick, and most families simply wait them out.
Every date here is computed from the Sun and Moon for the place entered, by the rule printed beside it.

A printed panchangam can differ by a day where an almanac reads a tithi at a different instant, and a family's own custom always comes first. Where the practice genuinely varies, the text says so rather than choosing for you.
