Why people convert GMT to Prague time
- Scheduling a call from GMT to Prague: a 10:00 AM start in GMT lands at 12:00 PM in Prague, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both GMT and Prague are inside the 9-to-5 working day between 9:00 AM and 3:00 PM GMT time (11:00 AM–5:00 PM CEST). That is roughly 6 hours of usable overlap.
- Coordinating a GMT-based team with Prague contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM GMT" is unambiguous; "3 PM" across a +2h gap is not.
- Block 9:00 AM–3:00 PM GMT as the recurring meeting window if you work primarily from GMT and need Prague colleagues present.
- Prague: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
