When does daylight saving time start and end?

It depends on the country. The US and Canada go forward on the second Sunday in March and back on the first Sunday in November. The EU and the UK go forward on the last Sunday in March and back on the last Sunday in October. Southern-hemisphere countries such as Australia, New Zealand and Chile do the opposite: forward in spring (September or October) and back in autumn (March or April).

Why does the time difference between two cities change during the year?

Because the two places change their clocks on different dates, or only one of them does. New York and London are 5 hours apart most of the year, but for two or three weeks in March and one in November they are 4 hours apart. The time zone converter applies each place's rules for the date you pick.

Do my Cal.com bookings move when the clocks change?

No. A booking is stored as an instant in time and shown to each person in their own current time zone, so a meeting at 10:00 in New York stays at 10:00 in New York, and the London guest sees it move from 15:00 to 14:00 for the weeks the two zones are out of step.
