Here are a few examples of national holidays with changing dates in December:
- Hanukkah (Jewish communities): Hanukkah, also known as the Festival of Lights, is an eight-day Jewish holiday that commemorates the rededication of the Holy Temple in Jerusalem. The date of Hanukkah changes each year based on the Hebrew lunar calendar and usually falls in December, but can also occur in late November.
- Christmas Day (Many countries): Christmas Day, which celebrates the birth of Jesus Christ, is observed on December 25th each year. If the holiday falls on a weekend, it may be observed on the closest weekday for public institutions and schools in some countries.
- Boxing Day (Commonwealth countries): Boxing Day is a public holiday observed in many Commonwealth countries on December 26th. If the holiday falls on a weekend, it may be observed on the closest weekday for public institutions and schools.
- St. Lucia’s Day (Sweden): St. Lucia’s Day, also known as the Festival of Light, is a Swedish holiday that honors St. Lucia, a Christian martyr. It is observed on December 13th each year. If the holiday falls on a weekend, it may be observed on the closest weekday for public institutions and schools.
- Kwanzaa (African-American communities): Kwanzaa is a week-long celebration of African heritage, unity, and culture observed from December 26th to January 1st. While not a public holiday, it is a notable event with changing dates that affect cultural and community activities.
Please note that not all of these holidays fall in December every year or are strictly tied to December. 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.
