The Jerusalem Light Festival (June) transforms the Old City walls and alleys with large-scale light installations and projections. The Israel Festival (May-June) brings international theater, dance, and music performances across the city. The Jerusalem Sacred Music Festival (September) stages concerts in churches, synagogues, and historic halls. Major religious holidays, Passover, Easter (celebrated on different dates by Western and Orthodox churches), Ramadan, and Sukkot, bring both larger crowds and unique seasonal atmosphere, but can also mean site closures and shifted opening hours.
