The Time-Zone Rendezvous
Solve eight clock puzzles using fixed October 18, 2026 UTC offsets: convert meeting times, check availability windows, and sort cities by local clock time.
All offsets are fixed assumptions for October 18, 2026, and the availability windows are invented. Nothing uses a live clock, so reason only from the offsets given in each puzzle.
Your choices are summarized at the end, and any tasks with right answers are checked separately. Progress is kept in this browser only so you can resume.
