About the time in Osa
If you are coordinating from another country, the shortcut is the working window: a normal Osa day of 09:00–17:00 falls between 15:00–23:00 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.
Osa runs on America/Costa_Rica, which puts the city UTC −6 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Sunrise today lands at 05:25 and sunset at 05:47 local time, giving 12h 22m of daylight. Those figures come from the city's own coordinates (8.84, -83.42) rather than a country-wide average, so they match what you would actually see from a window in Osa.
