About the time in Great Falls
Great Falls runs on America/New_York, which puts the city UTC −4 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.
If you are coordinating from another country, the shortcut is the working window: a normal Great Falls day of 09:00–17:00 falls between 13:00–21:00 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.
Great Falls is on daylight saving time at the moment, which is why the offset reads UTC −4 instead of its winter value. Clocks go back on 1 November 2026, and anything scheduled across that date shifts by an hour.
