Call United Kingdom from Indonesia

When calling internationally, it's important to consider time zone differences to ensure you're calling at a convenient time.

When calling Indonesia, note that the country spans three time zones: UTC+7 (Western), UTC+8 (Central), and UTC+9 (Eastern), with most major cities like Jakarta and Bali in UTC+7. For optimal connection times, call during Indonesian business hours (9 AM-5 PM local time) and consider that Indonesia does not observe daylight saving time, making time calculations consistent year-round. When calling the United Kingdom, which operates on GMT (UTC+0) in winter and BST (UTC+1) in summer, aim for late morning to early afternoon your time if you're calling from the Americas, or early evening if calling from Asia to catch UK business hours (9 AM-5 PM). Remember that the UK switches to Daylight Saving Time on different dates than many countries, typically the last Sunday in March and October, so verify the current time difference before important calls.
