Questions
How do I work out the time difference between two cities?
Find the time zone of each city, then count the hours between them. A city further east is ahead, so its clocks show a later time. Each comparison page does the sum for you and shows both live clocks.
Why does the gap sometimes change?
Many places move their clocks forward in spring and back in autumn, but not on the same dates. For a few weeks each year the gap between two cities can be an hour more or less than usual. Each page lists those dates.
Which cities are ahead?
Places further east are ahead. For example, Tokyo is ahead of London, and London is ahead of New York.
