Only the names actually in use are listed. A blank script is not an omission: the day may simply not be kept there, or be kept under a different festival's name.

UTC+5:30

The date of a festival depends on the place: 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.

When it falls next

Looking for the calendar this day belongs to

This day does not fall again in the next three years at this place. A few days are tied to the solar month rather than to the civil year, so a year can hold two of them or none.

What the day is

The eighteenth day of Aadi, when the Kaveri and the other rivers are in flood from the monsoon and the water is thanked for the year's crop. Families go to the riverbank or the canal with cooked rice in five or nine colours, float lamps and small offerings, and eat beside the water. Newly married couples are often taken along, since the day is held to bless a household's increase.

Festival Days of celebration: the house is decorated, a feast is cooked and the temple is visited.

The hour

The rule in words

The daylight hours beside the water; the offering is made in the morning or the late afternoon, not after dark.

The fast

No fast is kept. The day is a picnic: coconut rice, lemon rice, tamarind rice, curd rice and sweet pongal are cooked and shared.

Where the regions differ

A Tamil Nadu river day, kept hardest in the Kaveri delta. Kerala and the Telugu country have no equivalent, though the whole south treats Aadi as a month of Amman worship.

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.

Positions are accurate to a few arc-minutes, enough for signs, stars and padas except within about half a degree of a boundary, which the pages point out. Nothing you enter leaves the browser.
