Clock time and sun time in Isle of Man
A time zone is an agreement, and the sun does not follow it exactly. Douglas, the largest city in this zone, lies at about 4.5° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 18 minutes behind UTC. The clock is set to UTC. The sun is therefore highest in the sky at about 12:18 pm by the clock on standard time, and at about 1:18 pm while the clocks are moved (UTC+1). The clock runs ahead of the sun here, which means later sunrises and lighter evenings than the map alone would give. Other places in the zone, to the east or west of Douglas, 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
Douglas is about 54.1° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 17 hours 11 minutes. On the shortest, around 21 December, for about 7 hours 20 minutes. That swing of about 9 hours 50 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.
