Most Muslim shop owners close early or do not open on Friday, and Christians follow similar rules on Sunday. However, the markets and street stalls downtown remain open all week long, and Friday is their busiest day of the week. During Ramadan, the Muslim holy month of fasting, business hours are shorter. Museums are generally open every day except Tuesday, but opening hours sometimes vary. To be safe, bring a multi-purpose adapter.
American equipment requires both an adapter and a transformer.
Most varieties of adapters and transformers are readily available in electrical shops throughout Jordan. Electrical current in Jordan is reliable and uninterrupted. Any non-Arab visitor to Jordan, whether entering for business or as a tourist, needs an entry visa. The fee required for a visa, as well as the length of stay which is granted, depends on the visitor s nationality. Although entrance visas are obtainable at the airport for visitors arriving by airplane, those arriving by land must get a visa prior to arrival.
