Period with the employer for Form 16

This discussion seeks clarification on the correct employer period to be stated on Form 16, specifically whether it can run from the employee's joining date to the end of the financial year. The original poster provides an example of a period from 01/05/2016 to 31/03/2021 for AY 2021-22 and asks if this is acceptable. While it's usually the financial year itself, the poster wonders if this slight variation is permissible.
