What the day is
The full moon of the Sinhala month of Duruthu, 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 first visit of the Buddha to the island, to Mahiyangana, nine months after the enlightenment; the Duruthu Perahera at Kelaniya goes out for it.

- Buddha
- Kind
- Observance Days marked, watched or begun, without a fast or a feast of their own.
Significance
Duruthu opens the Poya year, and families remember the Buddha's first visit to the island, to Mahiyangana on the banks of the Mahaweli, to bring peace among its first people. It is also held to be the month in which the Buddha met King Bimbisara at Rajagaha, who gave the bamboo grove that became the first monastery. The Kelaniya temple near Colombo marks it with its great perahera, and families from the whole western province walk to it. Keeping the first Poya of the year well is held to set the tone for the eleven that follow.
How it is kept

What is cooked
Kiribath is made at home on the Poya morning and taken to the temple as dana. Around this season the first rice of the Maha harvest begins to be offered at the temples, and the family eats only after the monks have been served.
The hour
Clock times for Friday, 22 January 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 | 18:05 | the moment the sun goes down |
| Pradosha kala | 18:05 to 20:29 | the 2 h 24 min after sunset, the evening worship hour |
| Moonrise | 18:03 | the Moon rising at this place, the hour a moonrise vratam is broken |
Sunrise 06:36, sunset 18:05, 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 21:31 until 17:47 | then Krishna Prathamai until next day 14:13 |
| Nakshatra | Punarvasu until 10:25 | then Pushya until next day 07:32 |
| Rahu kaal | 10:54 to 12:20 (1 h 26 min) | the eighth of the daylight left alone for a beginning |
| Yamaganda | 15:13 to 16:39 (1 h 26 min) | the eighth ruled by Yama, also avoided |
| Gulika | 08:02 to 09:28 (1 h 26 min) | the eighth of Saturn’s son; what is done in it is said to repeat |
| Abhijit | 11:57 to 12:43 (0 h 46 min) | the midday muhurta, good for most things |
| Moonrise | 18:03 | moonset next day 07:11 |
For Friday, 22 January 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 keeps it with the Kelaniya Duruthu perahera, and Mahiyangana draws pilgrims who remember the first visit.
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.

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
Duruthu 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.
