Clock time and sun time in Los Angeles
A time zone is an agreement, and the sun does not follow it exactly. Los Angeles, the largest city in this zone, lies at about 118.2° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 7 hours 53 minutes behind UTC. The clock is set to UTC−8. The sun is therefore highest in the sky at about 11:53 am by the clock on standard time, and at about 12:53 pm while the clocks are moved (UTC−7). 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 Los Angeles, 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
Los Angeles is about 34° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 14 hours 25 minutes. On the shortest, around 21 December, for about 9 hours 53 minutes. That swing of about 4 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 Los Angeles.
- With India, in January: no shared office hour: 9:00 am here is 10:30 pm in India, and 6:00 pm here is 7:30 am there, so one side has to start early or stay late. In July: no shared office hour: 9:00 am here is 9:30 pm in India, and 6:00 pm here is 6:30 am there, so one side has to start early or stay late.
