Flip that calendar over to September and you know what happens? It (unofficially!) becomes pumpkin-everything season! You just know that fall is in the air when the favorite scents of crisp fallen leaves and apple pie take over your senses.
But September is also host to a whole bunch of cool, corny and cute days of observations. Of course, we know about Labor Day and Patriots’ Day (which honors September 11). But who knew that there was a Ginger Cat Appreciation Day, National Dog Walker Day, National Guacamole Day and National Gymnastics Day? We’ve put together a list of all the September 2026 holidays and observances, so you don’t have to miss a single one that you might be interested in celebrating!
There are even entire weeks in September that are dedicated to special causes, like National Waffle Week (September 7-13) or National Rehabilitation Awareness Week (September 14-20). And the month of September is also a time to bring awareness to several important causes like Childhood Cancer, Suicide Prevention, Hispanic Heritage and many more!
Keep on reading to find out all of the special-interest days and causes that are celebrated during the month of September!

Are There Religious Holidays in September?
Yes, in 2026, there are two major religious holidays in September. While Jewish holidays like Rosh Hashanah and Yom Kippur can fall in October, this year, both are in September.
One of Judaism’s high holy days, Rosh Hashanah, means “start of the year” in the Hebrew language. The two-day celebration of the Jewish New Year commemorates the creation of the world. The date for Rosh Hashanah varies every year on the modern Gregorian calendar since its observance begins on the first day of the seventh month of the Hebrew calendar. Rosh Hashanah 2026 will begin the evening of Friday, September 11, and end in the evening on Sunday, September 13, 2026.
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.
