What is a muhurat? Muhurta in plain English

A muhurat is a time chosen as suitable for doing something: the span picked for a wedding, a first payment, a journey or the start of new work. The word comes from muhurta, a unit of the traditional day, and in everyday use the two have grown together, so a family who say they have a muhurat for Tuesday mean they have been given a time rather than a forty-eight-minute span.

In the panchang, the traditional Hindu almanac, a muhurta is one thirtieth of a sunrise-to-sunrise cycle, about forty-eight minutes when day and night are the same length. Choosing a muhurat is something else: a branch of practice with its own literature, weighing several layers of the day against each other and against the chart of the person concerned. This note covers the word, the thirty muhurtas and how they are counted, what tradition looks at when it settles on a moment, and what such a choice honestly claims.

What the word means

The Sanskrit muhurta is a measure of time. Taken strictly it is a thirtieth of a whole day and night, so thirty of them fill one cycle from sunrise to the next. On a day where light and dark are evenly matched that works out at forty-eight minutes, a figure often quoted as though it were fixed, though it seldom is.

From that unit comes the sense in which most people meet the word. A muhurat, also written muhurtam in the south and mahurat in parts of the north, is a time judged fit for an undertaking. The shift is from a measure to a selection: a muhurat is a muhurta, or some other short span, that someone has looked at and found suitable. The classical literature on making that judgement is its own field, and the treatise cited most often in these notes, the Muhurta Chintamani, belongs to it. Of the usual English renderings, the auspicious time comes closest, though it suggests a verdict where tradition offers a preference.

The thirty muhurtas of a day and night

The thirty are not thirty equal slices of twenty-four hours. Tradition divides the daylight into fifteen muhurtas and the night into fifteen more, each set measured from the real events: the first fifteen run from your own sunrise to your own sunset, the second on to the next sunrise. A daylight muhurta is therefore a fifteenth of real daylight and a night muhurta a fifteenth of real darkness, and the two match in length only twice a year.

A worked example, with round illustrative figures rather than any real city: where sunrise falls at 6:00am and sunset at 6:00pm, the daylight runs 720 minutes, a fifteenth of it is 48 minutes, and all thirty muhurtas of that cycle agree. Stretch the daylight to fifteen hours and a daylight muhurta grows to 60 minutes while a night muhurta shrinks to 36. The farther a place lies from the equator, the wider that swing runs through the year, and two cities in one time zone differ on the same date because their sunrises differ. The Vedic day: why it starts at sunrise sets out the reckoning behind this.

The muhurta is one of several counts laid over the same cycle, and a reading usually looks at more than one of them.

Two of the thirty carry names in common use. The eighth of the fifteen daylight muhurtas is the abhijit muhurta, the span across local solar noon, which tradition counts among the steadier parts of the day and many panchangs pass over on Wednesdays; the note on abhijit muhurta shows how it is found. Near the other end sits the Brahma muhurta, second from the end of the night fifteen, running in the fixed reckoning from ninety-six to forty-eight minutes before the coming sunrise; the note on Brahma muhurta covers that count.

How tradition chooses a muhurat

Choosing a time is a matter of layers, and no single layer decides. In outline, tradition weighs:

• The vara, the weekday, each named for one of the seven grahas, the moving bodies of traditional astronomy. The vara in force is the one that began at the last sunrise, not the one the wall calendar turns to at midnight.
• The choghadiya, eight named parts of the daylight and eight of the night. Amrit (nectar), Shubh (good), Labh (gain) and Char (moving) are the four tradition favours; Udveg (restlessness), Kaal (time) and Rog (illness) are the three it sets aside. What is choghadiya? gives the order and how the weekday sets it.
• The hora, twelve planetary hours by day and twelve by night, each ruled by a graha, running in one unbroken sequence from sunrise. The note on the hora covers the ring of lords.
• The muhurta, the fifteen and fifteen described above, with abhijit the one most often brought into a decision.
• The lunar reckonings, chiefly the tithi, the lunar day, and the nakshatra, one of the twenty-seven equal star divisions along the Moon's path.
• The periods set aside, Rahu Kaal, Yamaganda and Gulika, three classical daytime spans, each filling one of eight equal parts of the daylight, with the part fixed by the weekday. The guide to Rahu Kaal, Yamaganda and Gulika explains how those are counted.

For a particular person, tradition adds the chart. Tarabala counts from the birth nakshatra to the nakshatra of the day and reduces the count to one of nine taras, of which tradition favours five. Chandrabala counts the day's Moon sign from the natal Moon sign and reads the house that falls out, some houses counting favourable and others weaker.

A practitioner choosing a wedding muhurat weighs all of that and more besides. This is why such a time is asked of a person rather than looked up: the layers pull against each other, and deciding which to honour is the skill. Practice varies by region, by lineage and by family, and where a household follows a particular panchang or astrologer, that is the practice to follow.

What a chosen time does not settle

The limits are worth stating plainly, because the word carries more weight in English than the tradition asks of it. A muhurat is a judgement that a stretch of time suits a kind of work. It is not a forecast of how the work will go, and the classical literature does not present it as one: tradition offers a rhythm to keep rather than a result to expect.

Nor is there one answer to find. Two panchangs can give different muhurats for one occasion in one city, because they follow different conventions: whether the abhijit span counts on a Wednesday, whether a night muhurta is a fifteenth of the real night or a fixed count of minutes, which ayanamsa, or offset between the sidereal and tropical zodiacs, is used. A disagreement between two sources is usually about convention rather than a mistake by one of them.

How Sumuhurta relates to the muhurat

Sumuhurta, the iPhone app this site is about, works with some of these layers and leaves the rest alone. It reads the choghadiya, the hora, the abhijit muhurta around local noon and the Brahma muhurta before dawn, and weighs them against the person's birth chart. What it produces is not a muhurat for an occasion but one to three personal windows in each sunrise-to-sunrise cycle, day or night, running roughly twenty to a hundred and fifty minutes and never crossing sunrise or sunset. Each carries a plain-English quality, Clear run, Sharp or Steady, and a quiet attribution naming the hora and the choghadiya at its middle, in the form Mercury hora · Labh. The rule governing where a window may fall at all reads:

Every personal window Sumuhurta surfaces is calculated to avoid Rahu Kaal, Yamaganda, Gulika, and the Kaal, Rog and Udveg choghadiya periods.

That rule is narrow on purpose, and the distance between it and the practice described above is the honest part. The app does not perform a complete electional-muhurta assessment, the fuller traditional work of choosing a moment for one occasion, which weighs many more factors. It does not replace a full panchang: there is no table of the thirty muhurtas on any screen, no choghadiya or hora tables, and no tithi or nakshatra tables. It offers no remedies and no compatibility reading, shows no score or rating, never marks any part of the cycle as a bad time, and does not predict outcomes. It never calls a window a muhurat, because that is a judgement it is not in a position to make. For a time chosen once, a full panchang or a qualified practitioner is the right place to go. How it reads the day covers the rest of the calculation.

Common questions

What is the difference between muhurat and muhurta?

A muhurta is the unit of time, a thirtieth of a day and night, counted as a fifteenth of the real daylight or the real night. A muhurat is a time chosen as suited to an undertaking, and in everyday speech the word usually means that chosen time rather than the measure.

How long is a muhurat?

Used for the unit, it is a fifteenth of the daylight or of the night, which is forty-eight minutes only when the two are equal. Used for a chosen time, the span is whatever the person choosing it marks out, and may be shorter or longer than one muhurta.

Can I work out a muhurat myself?

The counted layers are plain arithmetic once you have your local sunrise and sunset: dividing the daylight into eight, twelve or fifteen parts needs nothing more than those two times. Weighing the layers against each other, and against a chart, is the part tradition leaves to a practitioner.

Is the muhurat the same everywhere on a given day?

No. Every division here is measured from the local sunrise, so the spans differ between two cities in one time zone and shift through the year in each of them.

Does the app give a muhurat for a wedding?

No. It shows one to three personal windows in each cycle for ordinary daily work, and never presents them as a muhurat for one occasion. Choosing a time for a wedding is electional work for a qualified practitioner.
