Are There Religious Holidays in September?

No, in 2024 there aren't any major religious holidays in September. While Jewish holidays like Rosh Hashanah and Yom Kippur can fall in September, this year, they're in October.

And while it's not a major holiday, some Christians do celebrate The Birth of the Virgin Mary (also known as the Nativity of the Virgin Mary) on September 8 each year. The exact date that Mary, the mother of Jesus, was born was not recorded in modern scripture. But the date of September 8 was chosen centuries ago by the Eastern Church, which begins its church calendar in September.

Does September 2024 Have a Full Moon?

The full moon—called the Harvest Moon in September—will appear on Tuesday, September 17, 2024. The full moon that rises nearest to the autumn equinox is traditionally called the Harvest Moon, so that name can be used for either September or October’s full moon. That's why September 2024's full moon is called the Harvest Moon, since the Autumn Equinox date is September 22, 2024. This is also the second supermoon of 2024.
