Choosing a wedding date, and why Mercury retrograde is not the real test

If you are choosing a wedding date and you have been told to avoid Mercury retrograde, you have been given the wrong filter. Mercury going retrograde is not what a vivah muhurat is judged on in this tradition. The periods actually kept clear are the ones when Jupiter or Venus is too close to the Sun to be seen, the four months of Chaturmas, and the weeks when the Sun is in Sagittarius or in Pisces.

That is the short answer. Below is what each of those means, why the Mercury retrograde advice travelled so far anyway, and how a date is actually settled.

What a muhurat is deciding

A muhurat is not a lucky number. It is a set of conditions that the panchang can be checked against: the tithi, the nakshatra, the weekday, the yoga, and the rising sign at the moment the ceremony is performed. On top of that sit two more layers. First, the season, meaning whether the calendar permits marriages at all in that stretch. Second, the two people, meaning their own charts and particularly their Moon positions.

A good muhurat is the point where those three agree. Most of the work of finding one is elimination, which is why the list of periods to avoid is longer and more definite than any list of good dates.

Guru asta and Shukra asta: the real exclusions

Jupiter and Venus are the two planets tradition treats as essential to a marriage. Jupiter for the sanctity and the continuity of the household, Venus for the union itself.

When either of them comes too close to the Sun in the sky, it is lost in the glare and cannot be seen at dawn or dusk. In Sanskrit this is asta, and in plain terms the planet is combust. Tradition holds that a marriage should not be performed while Jupiter or Venus is in this state, and this rule, not Mercury retrograde, is the one that removes whole months from a wedding calendar.

Computed on the usual orbs, and rounded to the day, the recent and coming windows are roughly these:

• Venus close to the Sun: until about 17 February 2026, again around 18 to 30 October 2026, and a long stretch from about 7 July to 18 September 2027.
• Jupiter close to the Sun: about 15 July to 13 August 2026, and about 17 August to 15 September 2027.

Different schools use slightly different degrees for combustion, so the boundary days vary by a day or two between panchangs. Check the panchang your family follows before fixing anything close to an edge.

Chaturmas, and the Sun in Sagittarius or Pisces

Chaturmas is the four month period beginning at the Ekadashi in Ashadha, when Vishnu is said to sleep, and ending at the Ekadashi in Kartik, when he wakes. In most communities weddings pause for it. The dates move each year with the lunar calendar, so this is one to read from the panchang rather than memorise.

Separately, in much of north and central India, marriages are avoided while the Sun is in Sagittarius and while it is in Pisces. These are fixed and easy to look up. In 2026 the Sun entered Pisces on 15 March and left on 14 April, and enters Sagittarius on 16 December. In 2027 the Pisces stretch runs 15 March to 14 April again, and Sagittarius begins 16 December.

An extra lunar month, adhik maas, is also kept clear when one occurs.

A few days in the year run the other way and are treated as auspicious without any calculation at all. In Maharashtra these are the sade teen muhurat, described in the piece on Gudi Padwa. Those days are used for beginnings and purchases rather than for weddings, which still need the full check.

So where did Mercury retrograde come from

Mercury turns retrograde three or four times a year. In 2026 it did so from about 26 February to 21 March, from 29 June to 24 July, and from 24 October to 13 November. In 2027 the first window runs roughly 9 February to 3 March.

The idea that these are bad for weddings comes from a different astrological tradition, where Mercury retrograde is read as a period of misunderstandings, delayed paperwork and travel trouble. It spread widely online because it is easy to write about and easy to feel: everyone has had a contract go slowly.

In classical vivah muhurat, retrogression of Mercury is not one of the tests. What a muhurat cares about with Mercury is whether it is combust or badly placed at the moment of the ceremony, and that is a much narrower condition. If a date passes every real test and Mercury happens to be retrograde, tradition does not reject it.

I am not going to tell you that retrograde Mercury means nothing at all. What I will say is that ranking it above Guru asta is like checking the paint on a house before checking whether it has a roof.

What the two charts add

Once the calendar allows a stretch, the couple's own charts narrow it. The Moon positions matter most. The nakshatra the Moon occupies on the day, and its relationship to each person's birth Moon, is checked, along with the rising sign at the ceremony hour so that the 7th house of the muhurat chart is not damaged.

This is the part that cannot be done from an article. Two couples marrying in the same month will often be given different dates, and that is not inconsistency. It is the whole point of the exercise. If you are at this stage, this is the sort of thing a reading is for. Note also that Guna Milan, the matching done before a marriage is agreed, is a separate exercise from the muhurat. One asks whether the pair suits. The other asks when to hold the ceremony.

An honest word about all of this

A muhurat is a tradition of care. It is a family saying that this day matters enough to be chosen rather than defaulted to. That is worth something regardless of what you believe about planets.

What it is not is insurance. I have seen marriages held on beautifully chosen dates end badly, and marriages held on ordinary dates last a lifetime. Anyone telling you that a wrong date will cause misunderstandings, money trouble and ill health is frightening you into a booking. Choose a date carefully, then stop worrying about it and go and get married.

Questions people ask

Can we marry during Mercury retrograde. Yes. It is not a disqualifying condition in vivah muhurat. Check Guru asta, Shukra asta, Chaturmas and the Sun's position first, and settle the date on those.

Why does my panchang give different combustion dates from another one. Because schools use slightly different degree limits for a planet being combust, and because panchangs differ in how they calculate. Follow one panchang consistently rather than combining two.

Do we need a muhurat if the venue is only free on one date. Then you are choosing between the best hour on that date and moving the wedding. In practice an astrologer will find the best window within the day you have. That is a legitimate way to do it, and far better than forcing a date nobody can attend.
