Daylight is cut into eight equal parts, and the first one always belongs to the weekday’s own ruling planet — Sunday to the Sun and so Udveg, Monday to the Moon and so Amrit. Because the other seven parts are always the same seven names, the opener alone decides the day: Monday averages 0.675 against Saturday’s 0.596.
din ka choghadiya — the daytime table, weekday by weekday, choghadiya, chogadia, shubh muhurat
Sunrise to sunset, divided by eight. Which name each weekday opens on, why it opens there, and what that single choice does to the whole day.
Din ka choghadiya is the daytime half of the system, and it is the half most people actually use, because most errands happen between sunrise and sunset. The construction is short enough to state in one line: take the interval from sunrise to sunset, divide it into eight equal parts, and label them from a fixed seven-name cycle starting at the weekday’s lord.
Everything else on this page follows from that line. The cycle never changes order — Udveg, Chal, Labh, Amrit, Kaal, Shubh, Rog, and back to Udveg — so the only variable between one weekday and the next is where you enter it. Seven names into eight slots also means the eighth slot repeats the first, which is why every weekday’s daylight both begins and ends on the same choghadiya.
That repeat is not cosmetic. It is why the opener counts twice, and it is the reason the seven weekdays are not equally favourable in daylight even though they contain identical names. Each day’s eight slots total 4.45 plus the opener’s own score, and nothing else varies.
The seven choghadiya are named for the seven classical planets, and the seven weekdays are named for the same seven. A weekday’s daylight opens on the choghadiya of its own lord: Sunday belongs to the Sun and opens on Udveg, Monday to the Moon and opens on Amrit, Tuesday to Mars and opens on Rog, and so on down the week.
Read down the openers and the pattern is arithmetic: each weekday starts 3 places further along the cycle than the day before. That is the same +3 that governs the hora sequence, and it is why the openers walk Udveg → Amrit → Rog → Labh → Shubh → Chal → Kaal rather than in the cycle’s own order.
| Weekday | Lord | Opens on | Favourable slots (of 8) | Mean slot score |
|---|---|---|---|---|
| Sunday | Sun | Udveg | 4 | 0.604 |
| Monday | Moon | Amrit | 5 | 0.675 |
| Tuesday | Mars | Rog | 4 | 0.600 |
| Wednesday | Mercury | Labh | 5 | 0.662 |
| Thursday | Jupiter | Shubh | 5 | 0.666 |
| Friday | Venus | Chal | 5 | 0.646 |
| Saturday | Saturn | Kaal | 4 | 0.596 |
Mean slot score is the average of the engine’s per-name subscore across the eight daytime slots. It is a relative preference, not a probability of anything.
Add the seven subscores together and you get 4.45. Every weekday’s daylight contains all seven, exactly once, plus one repeat — the opener. So a weekday’s eight-slot total is 4.45 + (its opener’s score), and its mean is that divided by eight.
Run it: Monday opens on Amrit, the highest-scoring name in the set, and lands at 0.675. Saturday opens on Kaal, the lowest, and lands at 0.596. The gap between the best and worst daylight of the week is 0.079 — real, but far smaller than the folklore about "bad days" implies.
The practical reading is unglamorous and worth stating plainly: no weekday is short of usable daytime slots. The worst of them still carries four favourable ones out of eight. If you are choosing between Tuesday morning and Wednesday morning, the choghadiya difference is a tiebreaker, not a verdict.
Most tables print a three-way Good / Neutral / Avoid split. The engine does not think in three buckets.
Every choghadiya page on the internet will tell you Amrit, Shubh and Labh are auspicious and Udveg, Rog and Kaal are not. That is true and it is also where almost every page stops. The number that decides which window a muhurat search actually returns is finer than the label.
Chal is the case worth knowing. It sits in the favourable bucket — the engine labels it Good — but it scores 0.72 against Amrit’s 0.95. It is genuinely positive and genuinely the weakest of the four, which is exactly the nuance the tradition preserves when it calls Chal the traveller’s slot: good for what moves, unremarkable for what begins.
| Choghadiya | Lord | Engine label | Subscore |
|---|---|---|---|
| Amrit | Moon | Good | 0.95 |
| Shubh | Jupiter | Good | 0.88 |
| Labh | Mercury | Good | 0.85 |
| Chal | Venus | Good | 0.72 |
| Udveg | Sun | Bad | 0.38 |
| Rog | Mars | Bad | 0.35 |
| Kaal | Saturn | Bad | 0.32 |
Subscores are from CHOGHADIYA_SUBSCORE in the muhurat config — the same values folded into a window’s base score by blendChoghadiya(). They are internal weights, published here because they are more honest than a three-colour key.
Rows are weekdays, columns are the eight parts of daylight in order. Every row reads the same seven names in the same order; only the entry point moves. Read across for a day, or down a column to see how a fixed part of the morning changes character through the week.
| Weekday | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th |
|---|---|---|---|---|---|---|---|---|
| Sunday | Udveg | Chal | Labh | Amrit | Kaal | Shubh | Rog | Udveg |
| Monday | Amrit | Kaal | Shubh | Rog | Udveg | Chal | Labh | Amrit |
| Tuesday | Rog | Udveg | Chal | Labh | Amrit | Kaal | Shubh | Rog |
| Wednesday | Labh | Amrit | Kaal | Shubh | Rog | Udveg | Chal | Labh |
| Thursday | Shubh | Rog | Udveg | Chal | Labh | Amrit | Kaal | Shubh |
| Friday | Chal | Labh | Amrit | Kaal | Shubh | Rog | Udveg | Chal |
| Saturday | Kaal | Shubh | Rog | Udveg | Chal | Labh | Amrit | Kaal |
The eighth entry repeats the first — seven names into eight slots. That is the structure, not a typo.
These are conventional associations from mercantile and household practice, not computed outputs. They are here because the labels are meaningless without them.
Associations are conventional. The subscores in the section above are ours, and they only rank; they do not predict.
The claim is that a weekday’s daylight favourability is fully determined by its opener. Here is the arithmetic, which you can redo on paper.
| Step | Value |
|---|---|
| Sum of all seven subscores | 0.95 + 0.88 + 0.85 + 0.72 + 0.38 + 0.35 + 0.32 = 4.45 |
| Every weekday contains all seven, plus a repeat of its opener | total = 4.45 + opener |
| Monday opens on Amrit | (4.45 + 0.95) ÷ 8 = 0.675 |
| Saturday opens on Kaal | (4.45 + 0.32) ÷ 8 = 0.596 |
Monday is the most favourable daylight of the week and Saturday the least, by 0.079 of mean slot score — and you never had to open the grid to know it.
This ranks daylight only, and only on the choghadiya layer. Rahu Kaal, the tithi, the nakshatra and your own dasha all sit above it, and any of them can overturn the ordering for a specific decision.
Amrit, by the engine’s own ranking (0.95 against Shubh’s 0.88 and Labh’s 0.85). But "best" depends on the task: Labh is the stronger choice for anything with a profit motive and Chal for anything that physically moves, even though both score below Amrit.
Because it starts at the weekday’s ruling planet. Sunday belongs to the Sun and so opens on Udveg; Monday belongs to the Moon and opens on Amrit. Read down the week and each opener sits 3 places further along the fixed cycle than the last.
One eighth of the daylight at your location, so it is never exactly 90 minutes except by coincidence. In Indian cities it runs roughly 1h 17m in late December to 1h 45m in late June, and the exact figure depends on your latitude — the city pages in this cluster give the real range for eleven of them.
The names are, the clock times are not. The sequence depends only on the weekday, but each slot begins at your local sunrise, and sunrise varies by more than 40 minutes across India on the same date because the whole country runs one timezone.
Monday, which opens on Amrit and carries 5 favourable slots out of eight. Saturday is the weakest, opening on Kaal — though even it carries 4 favourable slots, so the difference is a preference, not a warning.
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.
