How to use it

Plan without doing time-zone math.

01

Choose the cities

Search by city, state, or country using Orbilora's worldwide database.

02

Enter the time

The date and time are interpreted in the first city's time zone.

03

Compare the day

See the conversion and identify business hours in both locations.

A time difference depends on the date

Compare a moment, not just a number

If the origin is at UTC−03:00 and the destination at UTC−07:00 on the selected date, 17:00 at the origin is 13:00 at the destination. That is a four-hour difference at that moment. Enter the actual appointment date: today's difference may change in the coming months.

Check the date and clock changes

From UTC−03:00 to UTC+09:00, 18:00 at the origin is 06:00 the next day at the destination. During daylight saving changes, some local times do not exist or occur twice. If the tool flags a nonexistent time, choose another; if it offers two occurrences, check which one matches your appointment.

Recurring meetings and travel

Recheck meetings around clock changes: countries can change on different dates. Business hours are only a reference, without personal schedules or holidays. When sharing, include the date, time and city. For flights, confirm local times on the ticket; comparing time zones does not calculate flight duration.
