Claude approaches timezone conversion as a reasoning problem, analyzing UTC offsets, daylight saving transitions, and business hour constraints across multiple regions simultaneously to find solutions that actually work for everyone involved. It evaluates trade-offs when perfect overlap is impossible, flags edge cases like upcoming DST transitions that will shift your meeting times, and explains clearly why a particular slot works or falls outside reasonable hours for specific participants.
