On 27 March the Iranian newspaper baztab reported that Iran leads the world in the number of public holidays, with 26. Including weekends, this means that Iranians get more than 1 day off for every 3 days of the year. Perhaps this helps explain how so many of them are able to work two jobs.

The article states that 16 of the 26 days are religious holidays, 6 are national holidays, 4 are government holidays, and that there is one national holiday that is not part of the annual New Year's celebration, which is called Oil Nationalization Day.

Wikipedia lists the names and dates of these holidays in an article titled Public Holidays in Iran. The Wikipedia article lists 15 religious holidays, while the baztab article says there are 16. The baztab article does not name the 16 so I am not sure which one is missing from the Wikipedia list.
