Ordinarily almost every Nepalese and Indian Panchanga gives important dates and times for celebrating marriages. The reader cannot rely on them as most of the dates given would not be free from important flaws. Moreover, the marriage dates selected would generally be in accordance with local usages.

For instance, a Hindu Indian or Nepali would not mind marriage being performed in lunar month of Ashadha (provided the Sun has not entered Cancer). But strong objection is taken to this by people living in Andhra and Karnataka of India. Apart from this, there is universal agreement all over Nepal and India as regards the time, weekday, constellation and planetary positions to be obtained at the time of marriage.
We are giving below the most standard methods employed by scholars, warranted by experience and sanctioned by the ancient sages.
The lunar months of Magha, Phalguna, Vaisakha and Jyeshta are good. Kartika and Margasira are ordinary. The rest are not auspicious. Some sages opine that marriages can be celebrated in Pushya and Chaitra provided the Sun is in Capricorn and Aries respectively.
The following lunar days, viz., from the 11th day (dark half) to New Moon, Riktha Thithis, 8th, 12th and 6th should be rejected. The best lunar days are the 2nd, 3rd, 5th, 7th, 10th, 11th and 13th (of the bright half).
Monday, Wednesday, Thursday and Friday are the best. Sunday and Saturday are middling. And Tuesday should be invariably rejected.
The best asterisms are Rohini, Mrigasira, Makha, Uttara, Hasta, Swati, Anuradha, Moola, Uttarashadha, Uttarabhadra and Revati. The first quarter of Makha and Moola and the last quarter of Revati are inauspicious and they should be rejected. Constellations not mentioned here are unsuitable and they should be avoided.
The following yogas should be rejected: Vyatipata, Dhruva, Mrityu, Ganda, Vajra, Soola, Vishkambha, Atiganda, Vyaghata and Parigha.
Vishti karana must invariably be discarded.
Among the zodiacal signs Gemini, Virgo and Libra are the best. Taurus, Cancer, Leo, Sagittarius and Aquarius are middling. The rest are inauspicious.
In the election of a Muhurtha for marriage, The most important considerations however are (a) The 7th house must be unoccupied by any planet, (b) Mars should not be in the 8th, (c) Venus should not be in the 6th, {d) the Lagna should not be hemmed in between malefics, (e) malefics should not occupy Lagna. and (f) the Moon in the election chart should have no association with any other planet.
Apart from the above, the usual Tarabala, Panchaka. etc., should be looked into. Elsewhere are given certain combinations which are supposed to neutralise adverse influeces. As far as possible, such combinations should be applied to secure a really propitious moment. Jupiter, Mercury or Venus in Lagna, malefics in the 3rd or 11th, would constitute a formidable force in rendering the Lagna strong.
Thus, it will be seen that the Hindus have devised an astrological means of judging marriage compatibility whereby the relations between the couple may stand the strain of maladjustment. If astrological advices are properly heeded to. there will be fewer tragedies than at present and less marital infidelity. Modern sexologists and sociologists will do well to study the theory behind the astrological rules bearing on marriage casting off their prejudices instead of criticising and condemning the system.
