Special Shabbatot are fixed Jewish Shabbat days, which precede or coincide with certain Jewish holidays during the year. Each one has a special name.

Shabbat Shuvah ("Sabbath [of] Return" שבת שובה) refers to the Shabbat that occurs during the Ten Days of Repentance, but is between (i.e. not including): the two consecutive Days of Rosh Hashanah; and the Day of Yom Kippur. Only one Shabbat can occur within the seven days period that falls between these dates. This Shabbat is named after the first word of the Haftarah (Hosea 14:2-10) and literally means "Return!" It is perhaps a play on, but not to be confused with, the word Teshuvah (the word for repentance).

Saint David's day (Welsh: Dydd Gŵyl Dewi) is the feast day of Saint David, the patron saint of Wales, and falls on the 1st of March each year. The first day of March was chosen in remembrance of the death of Saint David. Tradition holds that he died on that day in 589.^[1] The date was declared a national day of celebration within Wales in the 18th century.

Cross-party support resulted in the National Assembly for Wales voting unanimously to make St. David's Day a public holiday in 2000. A poll conducted for Saint David's Day in 2006 found that 87% of people in Wales wanted it to be a bank holiday, with 65% prepared to sacrifice a different bank holiday to ensure this.^[2] A petition in 2007 to make St. David's Day a bank holiday was rejected by the office of the British Prime Minister, Tony Blair.^[3]

Remembrance Day (Marshall Islands), formally known as Nuclear Victims’ Day and Nuclear Survivors’ Day, occurs on March 1st and is a national holiday in the Marshall Islands. The day honors the victims and survivors of nuclear testing done in the area in the 1950's.

Castle Bravo was the code name given to the first U.S. test of a dry fuel thermonuclear hydrogen bomb device, detonated on March 1, 1954 at Bikini Atoll, Marshall Islands, as the first test of Operation Castle. Fallout from the detonation poisoned the islanders who had previously inhabited the atoll.
