Moon calendar October 2026
Moonrise and moonset every day, illumination and phase, the four main phases, Chandra Darshan and the moonrise on Karwa Chauth and Sankashti Chaturthi.
Main phases
- Last Quarter
- New Moon (Amavasya ends)
- First Quarter
- Full Moon (Purnima)
Exact instants in Asia/Kolkata: the Moon is 0°, 90°, 180° and 270° east of the Sun in longitude.
Fasts broken at moonrise
- Karwa Chauth Thursday, 29 October 2026Moonrise:
- Sankashti Chaturthi Thursday, 29 October 2026Moonrise:
These fasts are broken after sighting the Moon; the time is the calculated moonrise at this place. Hills, buildings and haze can delay the actual sighting by several minutes.
Chandra Darshan (first crescent after Amavasya)
After the New Moon of 10/10/2026 21:19:
Monday, 12 October 2026 — look west after sunset: –
| Date | Moon age at sunset | Moonset after sunset | q | Visibility |
|---|---|---|---|---|
| Saturday, 10 October 2026 | — | — | — | F not visible (Moon too young or sets first) |
| Sunday, 11 October 2026 | 20.6 h | 6 min | -0.714 | F not visible (Moon too young or sets first) |
| Monday, 12 October 2026 | 44.6 h | 41 min | 0.470 | A easily visible to the naked eye |
Chandra Darshan is taken as the first evening after the New Moon on which Yallop's criterion (NAO Technical Note 69, 1997) predicts a naked-eye crescent (zone A or B). It assumes a clear sky and a flat western horizon, so actual first sightings can be a day later (or, with binoculars, earlier). The window runs from sunset to moonset.

Moonrise and moonset are for the civil day (midnight to midnight), so a day can have no moonrise or no moonset. Illumination and phase are at local noon.
About these calculations
Moonrise and moonset use the Moon's topocentric centre at the horizon (the convention of widely used Panchang publishers). Illuminated fraction k = (1 + cos i) / 2 with the phase angle i (Meeus, Astronomical Algorithms, ch. 48). Phases are the instants when the Moon–Sun longitude difference reaches 0°, 90°, 180° and 270°.
Checked against the US Naval Observatory phase times for September–November 2026 (within 1 minute), moonrise times published in Panchangs for Sankashti Chaturthi and Karwa Chauth 2026 in New Delhi (within 1 minute) and the 2026 Chandra Darshan dates of a published Panchang (11 of 12 months agree; in September the criterion gives the 12th, the published Panchang the 13th).
Traditions may vary by region and Panchang convention. Times are shown for the selected place, time zone and calculation profile.
