Personal timezones

When you travel, your events happen in different timezones. Lona can show each event in the timezone you were actually in — not a fixed home timezone.

How it works

Mark travel events with This is a flight and pick the timezone you're traveling to. Lona uses these transitions to segment your calendar: contiguous spans of days share the timezone you were in during that period. Days before your departure show in your origin timezone; days after your arrival show in the destination timezone.

To see this on your sheet, enable Personal Timezones in the time scale selector (the day-view settings). Your columns will shift to reflect your actual timezone at each point in time. Switch back to a fixed timezone anytime.

Adding a transition

1. Open an event that represents travel (a flight, train, or drive across timezones).
2. Toggle This is a flight.
3. Pick the arrival timezone — the timezone at your destination.
4. The event's start time stays in the departure timezone. The end time is interpreted in the arrival timezone.

You can mark multiple events to build a full itinerary — Lona chains the transitions together automatically.

What you'll see

With Personal Timezones enabled, your day columns adapt:

• Before departure: days render in your origin timezone
• Departure day: marked as a transition boundary
• After arrival: days render in the destination timezone
• In-flight: the transition gap between timezones

If you have a round trip, mark the return flight too. The columns after your return will shift back to your home timezone.

Turning it off

Toggle This is a flight off on the event to remove the transition. The end time stays the same wall-clock moment but is interpreted in the departure timezone. Your sheet columns will adjust accordingly.

To keep the transitions but view everything in a fixed timezone, uncheck Personal Timezones in the time scale selector.
