Hello Ansh

IELTS test dates are offered upto 4 times in a month making a total of 48 fixed test dates in one calendar year. The availability of IELTS dates in India may differ for the Academic and General Training module. While the Academic version is available on all 48 dates, the General Training version is available on 24 dates. In order to create flexibility and convenience, tests are mostly held on Saturdays and Thursdays.

The official website is www.britishcouncil.in

I hope this helps.

Thank You
