Gandhi Jayanti is an Indian national holiday that commemorates Mohandas Gandhi's birth on October 2.
This commemoration is one of the few that is commemorated
according to the common era calendar, rather than the lunar calendar that is
used to define most Hindu festivals, maybe because Gandhi is a recent figure or
because the occasion is a national holiday.
