Clock time and sun time in St Johns
A time zone is an agreement, and the sun does not follow it exactly. St. John's, the largest city in this zone, lies at about 52.7° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 3 hours 31 minutes behind UTC. The clock is set to UTC−3:30. The sun is therefore highest in the sky at about 12:01 pm by the clock on standard time, and at about 1:01 pm while the clocks are moved (UTC−2:30). That is a close match: clock and sun agree to within a quarter of an hour. Other places in the zone, to the east or west of St. John's, see the sun peak a little earlier or later. Through the year the figure also drifts by up to a quarter of an hour either way.
How long the day is
St. John's is about 47.6° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 15 hours 59 minutes. On the shortest, around 21 December, for about 8 hours 26 minutes. That swing of about 7 hours 33 minutes between summer and winter is the reason clocks are moved here: the extra summer daylight is shifted from the early morning to the evening.
Office hours shared with other places
If both sides work from 9 am to 6 pm, these are the hours when a call falls inside the working day at both ends. Times are for St Johns.
- With India, in January: no shared office hour: 9:00 am here is 6:00 pm in India, and 6:00 pm here is 3:00 am there, so one side has to start early or stay late. In July: 9:00 am to 10:00 am here, which is 5:00 pm to 6:00 pm in India (1 hour shared).
- With London, all year: 9:00 am to 2:30 pm here, which is 12:30 pm to 6:00 pm in London (5 hours 30 minutes shared).
- With New York, all year: 10:30 am to 6:00 pm here, which is 9:00 am to 4:30 pm in New York (7 hours 30 minutes shared).
