Current Time in Indian/Reunion Time Zone

Overview and Geographic Scope

The Indian/Reunion zone applies exclusively to the island of Réunion, a French department located east of Madagascar. It is one of several IANA zones sharing the UTC+04:00 offset, alongside zones such as Asia/Dubai, Asia/Muscat, Indian/Mauritius, and Indian/Mahe. The offset is constant throughout the year, meaning Réunion does not observe daylight saving time. The abbreviation for the standard time is +04, often referred to as Réunion Time (RET).

Offset and Abbreviation

The standard offset for Indian/Reunion is UTC+04:00, which is 4 hours ahead of Coordinated Universal Time. This offset is denoted as +04 in the IANA time zone database. Because there is no daylight saving, the offset remains unchanged all year. The abbreviation RET is commonly used in schedules and communications, though it is not an official IANA designation.

Daylight Saving Time Behavior

Indian/Reunion does not observe daylight saving time. The offset is fixed at UTC+04:00 throughout the year. This means there are no clock changes in spring or autumn, providing a constant time reference for residents and businesses. The absence of DST simplifies scheduling, as there is no need to adjust for seasonal shifts.

Countries and Cities

The only territory using Indian/Reunion is Réunion. The anchor city is Saint-Denis, the capital. Other major settlements include Saint-Paul, Saint-Pierre, and Le Tampon. While other zones at the same offset include cities like Dubai (Asia/Dubai), Baku (Asia/Baku), and Muscat (Asia/Muscat), these are separate administrative zones with distinct histories and rules.

Practical Guidance for Scheduling

For business and personal scheduling, understanding the offset is key. When it is 12:00 UTC, it is 16:00 in Réunion. Compared to major financial centers: when it is 09:00 in New York (UTC-05:00 standard), it is 16:00 in Réunion (UTC+04:00). During New York's daylight saving time (UTC-04:00), the difference is 8 hours. For London (UTC+00:00 standard), the difference is 4 hours; during British Summer Time (UTC+01:00), it is 3 hours. For Dubai (also UTC+04:00), there is no time difference. For Mumbai (UTC+05:30), Réunion is 1 hour and 30 minutes behind. These relationships help in planning calls and meetings across time zones.
