Now I know I am cooking a regular daily meal. I should prepare my dish in time, else it upsets the balance of environment.
Its only an annual event, so I better do it on time. My target or scheduled date is July 31 every year.
Sometimes Government gives me a one-time concession or extension of this date, where due to some external reasons, it thinks prudent to extend this timeline. For example for the financial year 2019-20 (assessment year 2020-21), the tax return filing date stands extended from July 31, 2020 to November 30, 2020 due to external conditions.
