Here are a few examples of national holidays with changing dates in September:
- Labor Day (United States and Canada): Labor Day is a public holiday that honors the contributions of workers and the labor movement. It is observed on the first Monday of September each year in the United States and Canada, so the date changes annually.
- Rosh Hashanah (Jewish communities): Rosh Hashanah is the Jewish New Year and a significant religious holiday. The date of Rosh Hashanah changes each year based on the Hebrew lunar calendar. It usually falls in September but can also occur in early October.
- Autumnal Equinox Day (Japan): Autumnal Equinox Day, also known as Shūbun no Hi, is a Japanese national holiday that marks the changing of seasons. It is observed on the day of the autumnal equinox, which usually falls around September 22nd or 23rd. The date changes each year due to the astronomical event.
- Brazilian Independence Day (Brazil): Brazilian Independence Day, also known as Sete de Setembro, celebrates Brazil’s independence from Portugal. It is observed on September 7th each year. If the holiday falls on a weekend, it may be observed on the closest weekday for public institutions and schools.
- Yom Kippur (Jewish communities): Yom Kippur, also known as the Day of Atonement, is the holiest day in Judaism. It is observed on the tenth day of the Jewish month of Tishrei, which usually falls in September or early October. The date changes each year based on the Hebrew lunar calendar.
Please note that not all of these holidays fall in September every year or are strictly tied to September. However, they are examples of holidays that may occur around this time and have changing dates due to various factors such as the day of the week, religious calendar systems, or astronomical events.
