One correction in Mr. Sundaraman's view: as per the judgment of the Madras HC, if you have completed 240 days in the fifth year, it is deemed to be considered as having completed 5 years of service, making you eligible for gratuity.
However, many are unaware that 240 days of working in every year are absolutely necessary to fulfill the norms of continuous service in that particular year—even in the first four years of service—which should be noted.
After the completion of five years of service, as Mr. Sundar stated, 6 months and above are rounded off as one year, while less than 6 months are neglected. For a clearer understanding, I have enclosed the M-HC judgment copy and rules on 240 days for your reference.
Hope I made it clear.
