Choghadiya in Mumbai — slot lengths, sunrise anchor and the full grid

Mumbai’s daylight runs from 10h 58m in late December to 13h 17m in late June, so a choghadiya slot here is 1h 22m to 1h 40m — never the round 90 minutes people quote. With solar noon lagging clock noon by 38.5 minutes, the boundaries land at awkward times like 07:42 and 14:22, which is exactly why they get ignored.

In Mumbai, Maharashtra, a daylight choghadiya runs 1h 22m to 1h 40m, sunrise moves 1h 15m across the year, and solar noon sits 38.5 minutes behind the clock. All three computed at 19.08°N 72.88°E.

Mumbai has the least seasonal variation of the big northern-and-western metros and the most rigidly scheduled working day, which produces a specific mismatch: the grid is stable enough that people expect it to be memorisable, and offset enough that it never is.

A slot boundary in Mumbai falls on a round clock time roughly never. Sunrise moves from 06:00 in early June to 07:15 in mid-January, and every one of the eight daylight boundaries inherits that offset plus an eighth of a day length that is itself not a round number.

What follows is the real grid, computed at 19.08°N, 72.88°E, with the working-day collision made explicit rather than left for you to discover at 11:40.

The grid does not respect the 9-to-6, and the mismatch is systematic

On the longest day of the year Mumbai’s daylight runs 06:02 to 19:19, and the eight boundaries computed from it — printed in full further down this page — land on values like 07:42 and 14:20. Not one of them is on the hour or the half hour, and there is no reason they should be: the grid is anchored to sunrise, and sunrise does not consult a calendar.

On the shortest day, running 07:08 to 18:06, the same eight boundaries have shifted about an hour later and compressed by 18 minutes per slot — a different set of awkward numbers, with no relationship to the first set that you could hold in your head.

The consequence is not that choghadiya is impractical in Mumbai. It is that the only workable use is the reverse lookup — decide when you want to act, then check what is running — rather than trying to hold a favourable window in your head across seasons. The tradition’s own habit of naming the slot rather than the hour was better adapted to this than a modern calendar is.

How long one Mumbai choghadiya is, through the year

Sunrise, sunset and the resulting eighth at the year's four turning points, computed for 2026.

Mumbai sits at 19.08°N, and latitude is the only thing that sets slot length. Its daylight runs from 10h 59m on 22 December to 13h 17m on 21 June — a swing of 2h 18m — so one eighth of it moves between 1h 22m and 1h 40m. That is 17 minutes of variation in the same named slot.

Date	Sunrise	Sunset	Daylight	One day slot	One night slot
March equinox (20 March)	06:43	18:49	12h 07m	1h 31m	1h 29m
June solstice (21 June)	06:02	19:19	13h 17m	1h 40m	1h 20m
September equinox (22 September)	06:27	18:35	12h 08m	1h 31m	1h 29m
December solstice (21 December)	07:07	18:06	10h 59m	1h 22m	1h 38m

Across the whole year a Mumbai daylight slot runs 1h 22m to 1h 40m and a night slot 1h 20m to 1h 38m. At the equinoxes the two are equal — that is what an equinox is.

Where Mumbai's grid sits on the clock, and why

Sunrise in Mumbai runs from 06:00 on 5 June to 07:15 on 18 January. That is 1h 15m of movement in the first boundary of the day, and since every later boundary is measured from it, the whole grid travels the same distance.

Longitude adds a second offset that never changes. At 72.88°E, 9.62° west of the 82.5°E timezone meridian, solar noon in Mumbai falls at about 12:38 rather than 12:00 — 38.5 minutes after the clock, on every date of the year. Against 1h 40m and 1h 22m slots that is roughly a 39-to-47 per cent share of one slot, borrowed from a neighbouring city's table and never repaid.

The full daylight grid for Mumbai on 21 June

Sunday, sunrise 06:02, sunset 19:19 — the year's longest daylight and therefore its longest slots.

13h 17m of daylight, divided by eight, gives 100 minutes a slot. Sunday is ruled by Sun, so the sequence opens on Udveg at 06:02 and closes on Udveg at 19:19 — the eighth slot repeating the first, as it does on every weekday. Of the eight, 4 are favourable.

1	Udveg	Sun	06:02 – 07:41	avoid for starts
2	Chal	Venus	07:41 – 09:21	favourable
3	Labh	Mercury	09:21 – 11:01	favourable

The same eight slots on 22 December, compressed

Tuesday, sunrise 07:08, sunset 18:06: 10h 59m of daylight, 2h 18m less than 21 June had. Each slot has shrunk to 82 minutes from 100, and sunrise itself has moved 1h 06m later.

Compare the third row of each grid and the whole argument of this page is in one line: Labh ran 09:21–11:01 in 21 June and Chal runs 09:52–11:15 in 22 December. Same city, same position in the grid, no overlap at all.

Slot	Choghadiya	Lord	Clock time in Mumbai	Reading
1	Rog	Mars	07:08 – 08:30	avoid for starts
2	Udveg	Sun	08:30 – 09:52	avoid for starts
3	Chal	Venus	09:52 – 11:15	favourable
4	Labh	Mercury	11:15 – 12:37	favourable

8	Rog	Mars	16:44 – 18:06	avoid for starts

The night that follows 21 June in Mumbai

Sunset at 19:19 to the next sunrise is 10h 43m, so each night slot is 80 minutes — 19 minutes shorter than that same day's daylight slots, because midsummer is when the night is the compressed half. In 22 December the relationship inverts and Mumbai's night slots reach 1h 38m.

The sequence is not the day sequence continued: it starts on Shubh, ruled by Jupiter, where the daylight had started on Udveg. The slots after midnight still belong to Sunday, because the vedic day turns over at sunrise and not at 00:00.

Slot	Choghadiya	Lord	Clock time in Mumbai	Reading
1	Shubh	Jupiter	19:19 – 20:39	favourable
2	Amrit	Moon	20:39 – 21:59	favourable
3	Chal	Venus	21:59 – 23:20	favourable
4	Rog	Mars	23:20 – 00:40	avoid for starts
5	Kaal	Saturn	00:40 – 02:01	avoid for starts
6	Labh	Mercury	02:01 – 03:21	favourable
7	Udveg	Sun	03:21 – 04:41	avoid for starts
8	Shubh	Jupiter	04:41 – 06:02	favourable

Times after 24:00 are shown on the following morning's clock; the row still belongs to the previous weekday.

Mumbai against the other cities in this cluster

The two numbers that make one Indian city’s choghadiya different from another’s: how far its solar noon sits from clock noon, and how much its daylight swings across the year.

City	Solar noon vs clock	Annual day-length swing	Daylight slot range
Ahmedabad	+39.7 min	2h 50m	1h 20m – 1h 42m
Mumbai (this page)	+38.5 min	2h 18m	1h 22m – 1h 40m
New Delhi	+21.2 min	3h 39m	1h 17m – 1h 45m
Surat	+38.7 min	2h 35m	1h 21m – 1h 41m
Rajkot	+46.8 min	2h 44m	1h 21m – 1h 41m
Vadodara	+37.3 min	2h 44m	1h 21m – 1h 41m
Pune	+34.6 min	2h 14m	1h 23m – 1h 39m
Bangalore	+19.6 min	1h 32m	1h 25m – 1h 37m
Hyderabad	+16.1 min	2h 05m	1h 23m – 1h 39m
Jaipur	+26.9 min	3h 23m	1h 18m – 1h 44m
Chennai	+8.9 min	1h 33m	1h 25m – 1h 37m

A positive offset means the sun peaks after the clock says noon. All eleven cities are on one timezone, which is why the column has a 38-minute spread.

Building the grid by hand, from three numbers

Three facts produce the whole table: the weekday, the sunrise and the sunset. Nothing else is needed, and nothing else is used.

Step	Value
Sunrise and sunset	06:02 and 19:19 — 13h 17m of daylight
Divide by eight	797 ÷ 8 = 100 minutes, or 1h 40m per slot
Sunday's opener	Udveg — the choghadiya of Sun, which rules Sunday
Walk the fixed cycle	Udveg → Chal → Labh → Amrit → Kaal → Shubh → Rog → Udveg
Third boundary, as a check	06:02 + 2 × 1h 40m = 09:21

The third slot on 21 June in Mumbai is Labh, running 09:21 to 11:01, and the eighth is Udveg from 17:39. Every boundary follows from the same division, and the same three facts on any other date give that date's grid.

Use the city's own sunrise, never a neighbour's. The eleven cities in this cluster span 37.9 minutes of solar time on an identical clock.

Frequently asked

What is the choghadiya timing in Mumbai today?

Today’s eight boundaries depend on today’s sunrise and sunset in Mumbai and on the weekday. The structural answer is on this page — slots of 1h 22m to 1h 40m depending on the season — and the live per-date table is on the Choghadiya Today tool.

How long is a choghadiya in Mumbai?

Between 1h 22m and 1h 40m of daylight, and between 1h 20m and 1h 38m at night. The two halves move in opposite directions through the year and cross over within a few days of each equinox, when both sit near 1h 31m.

Is Mumbai’s choghadiya the same as Pune’s?

Close but not identical. Pune is about 120 km inland and slightly south, which puts its solar noon 3.9 minutes earlier than Mumbai’s and shortens its annual day-length swing from 2h 18m to 2h 14m. On a given date the two cities’ boundaries differ by a few minutes — usually ignorable, occasionally not.

What this page can NOT tell you

• These are geometric sunrise and sunset times at the city centre. A tradition that uses the visible sunrise over a real horizon — hills, buildings, haze — will differ, and it is not wrong to.
• The figures are computed for a fixed reference year so this page cannot go stale on the shelf. Sunrise repeats to within seconds across years, so they hold; they are still not a substitute for looking up an actual date.
• Choghadiya carries no personal component. Your chart, dasha and transits are absent from every number here, and two people in this city read exactly the same table.
• The favourable / avoid labels are conventional and they do not predict outcomes. They rank a preference between otherwise equal moments, which is a much smaller claim than the word "auspicious" usually carries.
• Mumbai’s horizon is a coastline to the west and buildings everywhere else. Computed sunset is the geometric one; the sun disappears behind something considerably earlier in most of the city, and the tradition’s own sunset is the visible one.

Choghadiya is a folk-electional convention, not a prediction. It labels slices of the day by tradition; it does not know what you are doing, who you are, or how it turned out. Treat a label as a preference, and never as permission or prohibition.
