Duration of share buy back procedure

How long does whole procedure of share buy back take? I mean from the closing date of tendering my share till the money get credited to account.

Looking back at the buyback of wipro, the duration was 15-20 days…So it might be the same

Buyback has to completed within 1 year of Announcement date.
So if you know the Announcement and Tender dates you can take a better guess as to how many days max will it take for the Money to be credited.

As per rule payment must be made within 10 working days after buyback closer .
