Amavasya — Next New Moon Dates, Exact Start and End Times

When is the next Amavasya? Computed new-moon tithi dates with the exact instant each window opens and closes, why calendars disagree on the date, and what the sunrise rule actually decides. Recalculated, never a stored year list.

amavasya, amavasya date, next amavasya, amavasya today, new moon tithi, amavasya time, when is amavasya

Amavasya is the lunar day on which the Moon finishes its circuit and sits alongside the Sun — the dark, moonless night that closes each lunar month. It is a tithi, not a calendar date: it begins and ends at exact instants, and lasts a little over or under a day rather than exactly one.

The next Amavasya falls on Wed 12 Aug 2026, opening at 02:05 on 12 Aug and ending at 23:18 on 12 Aug (New Delhi sunrise, IST (UTC+5:30)).

Because Amavasya is a window and not a day, the useful question is never just “what date” — it is *which day carries it*. A panchang answers that with one rule: the tithi in progress at sunrise names the day. That single convention is where almost every disagreement between two calendars comes from, and it is the thing most Amavasya pages leave out.

Everything below is computed rather than looked up. The table refreshes every time this page is built or opened, so it never becomes a stale list of one year’s dates.

The next fourteen Amavasyas

Start and end are the exact instants the tithi opens and closes, in New Delhi wall-clock time. The date column is the day a panchang would print — the day whose sunrise falls inside that window.

Computed 2026-08-08 · dates resolved for New Delhi sunrise, IST (UTC+5:30).

What the numbers actually say

Measured over 119 consecutive intervals from 2026-08-08, one Amavasya to the next falls between 29.283 and 29.823 days apart, averaging 29.538 days.

Across the same 120 windows the tithi itself runs from 20.18 to 26.58 hours, averaging 23.31 — and 68 of the 120 are shorter than a civil day, which is why a lunar day and a calendar day drift apart.

Occurrences per calendar year over the computed span — 2027: 13 · 2028: 12 · 2029: 12 · 2030: 13 · 2031: 12 · 2032: 12 · 2033: 13 · 2034: 12 · 2035: 13.

None of the 120 windows in this sample missed a reference sunrise, so every date above resolves under the primary rule.

What actually decides the date

A tithi is one twelfth-of-a-circle of separation between the Moon and the Sun. Amavasya is the thirtieth and last of them: the stretch in which the Moon has pulled to within 12° of the Sun and is about to pass it. The moment the Moon crosses the Sun’s longitude, the tithi ends and a new lunar month begins.

The Moon does not gain on the Sun at a constant rate — its orbit is elliptical, so it speeds up near perigee and slows near apogee. That is why a tithi is not a fixed length. Over the occurrences listed below, this page measures each window and prints the shortest, longest and average it found, so you can see the spread rather than take a number on trust.

The consequence is the part worth understanding: a tithi that runs shorter than the gap between two sunrises can begin after one sunrise and end before the next. No sunrise falls inside it at all. When that happens the tithi is called *kshaya* — lost — and calendars have to fall back on a secondary rule. Those are the dates on which two panchangs most often disagree, and this page marks them rather than hiding them.

Why the same Amavasya is a different date in different cities

The tithi window is a fact about the sky and is the same everywhere on Earth at the same instant. Sunrise is not. If a tithi opens at 19:58 in Delhi, then Delhi’s next sunrise falls inside it and Delhi prints that following day — but a city far enough west may still be in daylight, take its sunrise before the window opens, and print the day before.

This is not two calendars being wrong. It is one rule applied at two places. Every date on this page is resolved for New Delhi, because that is the reference most published Indian panchangs use; for anywhere else, treat a printed date as accurate to within a day and check the start and end instants in the table against your own sunrise.

If you want the answer for your own city rather than the reference meridian, the city panchang pages compute sunrise and the prevailing tithi locally.

What the day is used for

Amavasya is traditionally a day turned inward rather than outward. It is associated with the ancestors — tarpana and shraddha rites are offered on it — and with quiet, fasting and restraint rather than with beginnings. Because the Moon carries no light, classical texts treat it as a poor window for launching something that needs visibility or momentum, and a reasonable one for closing accounts, clearing, and rest.

That is a statement about traditional practice, not a prediction. Nothing on this page says an Amavasya will go badly for you; a tithi is a shared condition of the sky, identical for everyone alive that day, and it cannot distinguish between two people. Anything that claims to do that has to read a birth chart, not a calendar.

Amavasya — frequently asked

When is the next Amavasya?

The first row of the table above is the next one, with the exact instants the tithi opens and closes in New Delhi time. It recomputes rather than being a stored list, so it is current whenever you read it.

Is Amavasya always exactly 30 days apart?

No. Measured across the occurrences on this page, consecutive Amavasyas fall between roughly 29.3 and 29.8 days apart — never a round 30. The Moon travels an elliptical orbit, so the time it takes to catch the Sun again varies from month to month. The page prints the measured minimum, maximum and mean rather than a rounded figure.

Why do two calendars show Amavasya on different days?

Because a tithi is a window, not a day, and the printed date is decided by which sunrise falls inside that window. Two places with different sunrise times can therefore land on different dates for the same tithi. When the window is short enough that no sunrise falls inside it at all, calendars fall back on secondary rules that differ between traditions — those rows are marked on this page.

How many Amavasyas are there in a year?

Usually twelve, but not always — because the lunar cycle is just under 29.5 days, a calendar year occasionally holds thirteen. This page counts them rather than assuming a number.

Is Amavasya a bad day?

Traditionally it is treated as a day for rest, ancestral remembrance and closing things rather than starting them — not as a day that harms anyone. It is also the same day for everyone alive, so it cannot be good or bad for you specifically. Anything personal has to come from a birth chart.

What is the difference between Amavasya and a new moon?

They describe the same event from two directions. Astronomy marks the instant of conjunction — one moment. A tithi is the whole twelve-degree stretch leading up to it, so Amavasya is a window of roughly a day that ends at that instant.

What this page cannot tell you

• This page cannot tell you anything about you. A tithi is the same for every person on Earth that day — it carries no personal information at all, and any page that reads your future from a shared lunar day is guessing.
• Dates are resolved for New Delhi sunrise. Elsewhere the same tithi can land on the day before or after; use the exact start and end instants in the table, not the date, if you are far from that meridian.
• It does not name which lunar month each Amavasya belongs to (Mauni, Mahalaya, and so on). That needs the solar-ingress and adhika-maasa rules, which this page does not compute — so it does not claim them.
• It does not tell you which regional tradition your family follows. Where the primary sunrise rule fails, different panchang schools resolve the tie differently, and this page marks the ambiguity rather than picking a side for you.
• The underlying positions come from the shared analytical ephemeris, accurate to well within a tithi boundary for these purposes, but not the arc-second engine used for a full birth chart.

The other lunar days

• Purnima dates (full moon) — When is the next Purnima, how long is the full-moon tithi actually full, and how far is it from the new moon that follows?
• Ekadashi dates (the eleventh lunar day) — When is the next Ekadashi, and why are there not simply twenty-four of them in a year?
• Today’s panchang — tithi, nakshatra and muhurat computed for your own city rather than the reference meridian.
