About this calendar
September 2031 carries 6 holidays in total: 3 on the US secular calendar and 3 religious. Only 1 is a day off — a tinted cell here marks an observance, not a holiday from work.
Jewish and Islamic dates begin at sunset on the evening before the day shown, and the Islamic ones follow the Umm al-Qura calendar, where local moon sighting can move observance by a day. Hindu festivals are not listed: they are lunisolar and vary by region and by panchang, and a guess would be worse than an absence.
