Frequently asked questions
How do I schedule across time zones?
Pick the date and a time in the first zone, then read the time in the second. Check both sit inside working hours.
Why does the gap change during the year?
Regions switch to daylight saving on different dates, so the offset between them changes.
What time zone name should I use?
Use the IANA name, such as Europe/Paris.
Can I compare three zones?
Run the planner twice, once for each pair.
