- Finding shared working hours: both Prague and Japan are inside the 9-to-5 working day between 9:00 AM and 10:00 AM CEST time (4:00 PM–5:00 PM JST). That is roughly 1 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Prague is 3:00 AM in Japan makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a +7h gap is not.
