As per the Bombay Shops and Establishments Act, there are four national holidays, namely 26th January (Republic Day), 15th August (Independence Day), 1st May (May Day - Maharashtra Day), and 2nd October (Gandhi Jayanti). Apart from this, the Government of Maharashtra declares at the beginning of the year a list of holidays (including the above) under the Negotiable Instruments Act. To my knowledge, there is no other statute providing for additional holidays such as festival holidays, similar to the Festival and National Holidays Act in force in some other states like Karnataka or Delhi.
