The grandest holiday of all is Junkanoo, a carnival that came from slaves who made elaborate costumes and instruments such as goatskin drums. Junkanoo is celebrated on Boxing Day, the day after Christmas, and New Year's Day (the bands compete in all-night parades that start in the wee hours). Don't expect to conduct any business the day after the festivities.
During other legal holidays, most offices close, and some may extend the holiday by keeping earlier (or no) hours the day before or after.
In the Bahamas official holidays include New Year's Day, Majority Rule Day (Jan. 10), Good Friday, Easter, Easter Monday, Whit Monday (last Mon. in May), Labour Day (1st Mon. in June), Independence Day (July 10), Emancipation Day (1st Mon. in Aug.), National Heroes Day (Oct. 12), Christmas Day, and Boxing Day (Dec. 26).
