Time
In Indonesia time is written using the 24-hour clock. When speaking, the 12-hour clock is used. Parties are expected to be prompt for business appointments; however, for social engagements, people tend to arrive up to about one hour late. Except for airline flights, trains, and overnight buses, public transportation isn't formally scheduled, so travelers should be prepared to simply wait for the next vehicle.
Muslim prayer times occur five times a day: 4:30 a.m., noon, 4:00 p.m., 6:00 p.m., and 7:00 p.m. On Fridays, businesses, offices, and schools close by 11:00 a.m. for Friday prayers; some reopen later in the day, but many remain closed. Some establishments are open on Saturday, but not all. Almost everything is closed on Sundays.
