About the time in Saint-Louis
Clocks in Saint-Louis stay put all year. There is no summer-time switch to remember, so UTC +4 is what you will get in January and in July alike — useful if you book recurring calls with people in Réunion.
If you are coordinating from another country, the shortcut is the working window: a normal Saint-Louis day of 09:00–17:00 falls between 05:00–13:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
The zone identifier Indian/Reunion is the value you want in code, calendars and travel systems. Abbreviations change with the season, but Indian/Reunion keeps pointing at Reunion time whatever the date, which is why every timestamp on this page is built from it.
