Why does "wedding" Prohibit during July-August or in the Tamil month of Aadi? Why newly married bride were sent to their parents house in Tamil month of Aadi?

The monsoon months are the weakest months of the year, easily causing diseases due to change in the climate because of the pouring rains. Monsoon is strong during these days spreading diseases through water and air. That is why marriages, family celebrations and other communal activities are not held during this month.

These practices link the people to the age old sentiments and customs that have passed on to our modern generations traditionally. According to traditions this month is inauspicious.

The real meaning behind this has many scientific implications. If the bride conceives in this month, she will deliver the child in the second half of May (Chithirai), the hottest period of the year, which may harm both the child and the mother. Moreover, contagious diseases like small pox, measles, etc. are more prevalent during this time.

Another practical reason is that this season is the time for busy agricultural tasks of cultivation. All people have to focus their whole attention to agriculture, Rivers and streams are filled with water due to monsoon rains and men cannot waste their time in other engagements. They have to get up very early in the morning and involve themselves in their duties.
