About This Time Conversion

This page converts the local time between Vientiane, Laos (timezone Asia/Vientiane, currently ++7, GMT+7) and Reykjavik, Iceland (timezone Atlantic/Reykjavik, currently ++0, GMT+0). 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 Vientiane, the clock in Reykjavik 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 Vientiane and Reykjavik.
