Just putting my views on the topic..very true..2 day marriage(night marriage) is much more better than the one day marriage either from tradition point of view as well as grandeur.However why oneday marraiges are so famous now a days,there are some points which friends above have already discussed.
Foremost,to avoid any sort of disturbance or vandalism during marraige.After having few pegs our brothers just goes straight to seventh heaven,they feel like a king.In daytime atleast they are watched by seniors of family and can be controlled easily.
Second,i guess now a days people are so busy in their life style less days marraige will be their,it will be convinent for them.Earlier whole village was involved if any marraige is there,and the baratis were guest to whole village not just that person's whos hosting marriage.But with people migrating from villages they dont have ample space in their individual houses.So they have to book banquet halls etc to get it done.So more the no. of days will be marraige more will be expense.Now a days,People from Girl side just goes to groom city,rent a banquet hall and finish all ceremonies.Personally i feel,its not bad idea either.
Thirdly,I believe night marriages are more expensives atleast from lighting arrangements,generators etc.That too,if somehow electricity goes down,its usually a mess up during night time or rain pours in.
There may be many our points,hopefully other members will put in their views.
