Why Election in May?

There are less number of people coming out to vote in Gujarat this time as deadly heat wave has kept people in. Who do you think will stand in Q to vote in 45C with heat wave on? I really congratulate those (45%) who voted this time. But 45% is real bad number. I consider it failure of election. This is the time of a year when all schools in Gujarat (and most of India) give vacation to the students just because of unbearable heat. But when it comes to election, it has to be on time. Not after, not before...
I am not aware if there election commission has any right of flexibility in time for conducting election when present government is about to complete its term, but we must have rule which can allow election commission to take decision on conducting election +-2 month to avoid such situation.
