RET — Reunion Time
See what RET means, where it is used, its UTC+4 offset, and how to convert Reunion Time to other time zones.
Meaning and Usage
RET stands for Reunion Time and uses a fixed UTC+4 offset. It is the standard local time used in Réunion year-round.
No DST Changes
Reunion Time does not observe daylight saving time, so RET stays at UTC+4 throughout the year. This keeps scheduling consistent across all seasons.

How to Convert RET to Other Time Zones
Open the RET converter page: Go to https://www.xconvert.com/time-converter/ret-time-zone to open the visual comparison grid with RET pre-loaded. This page is useful when you need to line up work in Reunion Time with teams, vendors, or clients in other regions that run on different UTC offsets.
Add comparison cities: Click + Add City and search for the locations you want to compare against RET. A practical setup is to add the cities used by your remote team, customer support desk, or logistics partners so you can see where UTC+4 overlaps with their business hours on the same 24-hour grid.
Select a meeting window on the grid: Click Select to enter selection mode, then drag across the RET row to highlight a time range in purple; you can move it by dragging the center or fine-tune it with the left and right handles. This makes it easy to test whether a morning, afternoon, or evening slot in Reunion Time lands inside normal work hours for the other rows you added.
Export and share the result: Once a range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful for sending a confirmed meeting window to distributed teams so everyone sees the same event translated into their own local time.
About Reunion Time (RET)
RET stands for Reunion Time. Its standard offset is UTC+4, which means local time in RET is four hours ahead of Coordinated Universal Time throughout the year.
Reunion Time does not observe daylight saving time and has no counterpart, so there is no seasonal switch to an alternate RET-based abbreviation. That makes RET a fixed time standard for scheduling because the offset remains UTC+4 in every month.
RET shares the same UTC+4 offset with several other abbreviations, including ADT, AMT, AZT, D, GET, GST, KUYT, MSD, MUT, SAMT, and SCT. Even when the offset matches, it is still important to confirm the exact zone label in scheduling tools because abbreviations can refer to different regions and operational contexts.
RET and Daylight Saving Time
RET does not switch for daylight saving time. It stays on UTC+4 all year and does not move forward or backward seasonally.
Because Reunion Time has no DST counterpart, there is no separate summer or winter version to track. There are also no DST transition dates to remember for the current year, which simplifies recurring meeting planning and long-term calendar coordination.
This fixed offset is useful for teams that want predictable scheduling. If you set a recurring event in RET, the RET side of the meeting remains constant at UTC+4, even when other participating time zones may change their clocks seasonally.
Frequently Asked Questions
What does RET stand for?
RET stands for Reunion Time. It is the time zone abbreviation used for a fixed offset of UTC+4, so it stays four hours ahead of UTC year-round.
Is RET the same as GMT?
No. RET is UTC+4, while GMT is at UTC+0, so RET is 4 hours ahead of GMT. That means when it is 9:00 AM in GMT, it is 1:00 PM in RET.
Which cities use RET?
Specific city listings are not included here, but RET refers to Reunion Time as a named time standard. In practical scheduling, the most important detail is that RET remains on UTC+4 without seasonal clock changes.
What is the UTC offset for RET?
The UTC offset for RET is UTC+4. This means you add four hours to UTC to get Reunion Time, and that relationship stays the same throughout the year.
When does RET change for daylight saving time?
RET does not change for daylight saving time. There are no annual clock changes, no spring-forward date, and no fall-back date because Reunion Time does not observe DST.
Does RET have a summer time or winter time counterpart?
No. RET has no counterpart, so there is no alternate abbreviation used for a daylight saving version of the zone. This makes RET simpler to manage for recurring meetings because the abbreviation and offset remain the same.
Is RET the same as other UTC+4 time zones?
RET shares the UTC+4 offset with ADT, AMT, AZT, D, GET, GST, KUYT, MSD, MUT, SAMT, and SCT. However, matching offsets do not always mean the same regional time standard, so it is best to schedule using the exact zone or city label shown in your calendar or converter.
Why is RET useful for scheduling recurring meetings?
RET is useful for recurring scheduling because it stays fixed at UTC+4 and does not observe DST. That consistency reduces confusion when planning ongoing calls, support coverage, or project handoffs, especially if other participants are in regions that do change their clocks seasonally.
