This is especially useful for sending a production review meeting to a distributed team, creating a calendar event that automatically converts into each participant’s local time, or sharing a link with a travel coordinator arranging airport pickup and hotel check-in timing.
About Sidoarjo Time Zone
Sidoarjo uses the Asia/Jakarta IANA time zone, which operates at UTC+7 all year. In Indonesia, this time zone is known as WIB (Western Indonesia Time / Waktu Indonesia Barat), and it covers Java, Sumatra, and parts of western Indonesia, including major economic centers such as Jakarta, Bandung, and Surabaya. Because Sidoarjo is in East Java Province, its local clock matches Surabaya and the rest of Java’s business schedule.
Sidoarjo does not observe daylight saving time (DST), so its UTC offset stays fixed at +7 hours in every month of the year. That stability makes recurring scheduling easier for local businesses, factories, schools, and government offices, but international callers still need to account for seasonal clock changes in countries such as the United States, United Kingdom, and Australia. For example, the gap between Sidoarjo and London is 7 hours in winter and 6 hours during British Summer Time.
Within Indonesia, Sidoarjo’s time zone sits one hour behind Central Indonesia Time (WITA, UTC+8) used in places such as Bali and Makassar, and two hours behind Eastern Indonesia Time (WIT, UTC+9) used in Jayapura. That matters for domestic logistics, inter-island travel, and national coordination: a 10:00 AM meeting in Sidoarjo is 11:00 AM in Bali and 12:00 PM in Papua on the same day.
Sidoarjo City Details
Sidoarjo is a city in East Java, Indonesia, located at -7.4478°, 112.7183°, just south of Surabaya in one of the country’s most active urban-industrial corridors. Its position places it near major transport and manufacturing networks, making time coordination important for factory operations, freight movement, and business communication across Java and beyond.
The city has a population of 139,189, which makes it a significant local urban center rather than a small rural settlement. In practical terms, that means regular business activity, local government services, retail hours, commuting patterns, and regional connections that often follow the broader Surabaya metropolitan rhythm.
Sidoarjo uses the Indonesian rupiah (IDR) for all local transactions, and Indonesia’s country dialing code is +62. If you are calling a business, hotel, or local contact in Sidoarjo from abroad, you would dial +62 followed by the local number without the domestic leading zero.

For Tokyo, Sydney, and Dubai, the overlap is generally much easier because the time gaps are smaller and more suitable for standard business hours.
