Comfortable clothing and a willingness to listen are usually enough. Bring water if needed and check where shoes are left and whether photography is permitted.
For longer festivals, confirm duration, seating, accessibility and children’s arrangements. Ask before bringing flowers, fruit or other offerings.
Musical instruments, books, special clothes or a financial contribution are not compulsory. Any particular requirement should be specified in the event announcement.
For fasting days, use a locally verified calendar and take individual health considerations seriously.
