Origin, destination, and Zulu — at a glance
Enter your departure and destination airports, the planned local departure time, and an estimated time en route. The calculator returns origin local, destination local, UTC / Zulu departure and arrival, and the time on the clock back home when you land — DST-aware via each airport's time zone.

UTC / Zulu is the common reference aviation uses for flight plans, METARs / TAFs, and clearances. Origin and destination times are computed against each airport's IANA time zone, so daylight-saving transitions on the flight date are handled automatically.
How pilots use this
- Plan a long cross-country. Departing KLAX at 06:30 local for an arrival at KJFK shifts you three hours forward — the calculator gives you the destination clock time at landing and the Zulu times to file.
- Coordinate with passengers or FBOs. The "back at origin clock" line tells you what time it will be at the departure airport (and presumably whoever you left behind) when you touch down.
- Brief Zulu confidently. METARs, TAFs, and clearances run on Zulu. Both departure and arrival UTC times are shown side-by-side with the local equivalents.
- DST safe. The flight date drives the zone calculation, so a 30 March routing across the spring-forward weekend won't trip you up.
Pilot UTC / Zulu time converter FAQ
- What is Zulu time?
- Zulu time is the aviation name for Coordinated Universal Time (UTC) — the same clock used worldwide for METARs, TAFs, NOTAMs, and ATC clearances. This pilot UTC converter shows both the local clock at your departure and destination airports and the matching Zulu time, so you can file and brief without doing the math yourself.
- Does the converter handle Daylight Saving Time?
- Yes. Enter the flight date and the converter applies the correct IANA time zone for each airport on that date, so a flight across the DST changeover weekend uses the right offset on each side.
- How do I convert local time to Zulu for a future flight?
- Enter your departure airport, the local departure time, and the destination airport. The calculator returns Zulu departure, Zulu arrival, destination local time, and the "back at origin" clock — all in one view.
- Why does the destination time look different from a simple offset?
- Time-zone offsets are not always whole hours, and DST shifts mean the offset on flight day may differ from the offset today. The converter uses the airport's IANA zone, so India, Newfoundland, and other half-hour or 45-minute zones come out correctly.
- Is the pilot time-zone converter free?
- Yes, the UTC / Zulu converter is part of the free Aero Companion toolset. Why this is free.
