About This Time Conversion

This page converts the local time between London, United Kingdom (timezone Europe/London, currently ++1, GMT+1) and Jakarta, Indonesia (timezone Asia/Jakarta, currently ++7, GMT+7). TZSync uses the IANA timezone database so conversions always account for Daylight Saving Time, half-hour offsets such as India (UTC+5:30), and quarter-hour offsets such as Nepal (UTC+5:45).

When it is daytime in London, the clock in Jakarta reads a different hour, and possibly a different calendar day. Drag the time slider on this page to find an overlap where both cities are inside typical working hours (9 AM – 5 PM local time) — that overlap is your best window for meetings, calls, and collaboration between London and Jakarta.
