Where the sun is when you finish.
You stand at the middle of your horizon. The dots are the sun’s path that day, bright from the hour you finish to the light’s end. Move the hour, walk the year, or drag the sky to turn it.
Clocks go forward on 29 March and back on 25 October (GMT ↔ BST). Sunset moves from 6:28 PM to 7:29 PM on 29 March, and from 5:49 PM to 4:47 PM on 25 October.
How it knows.
Three kinds of evening light
Sunset is the sun’s upper edge on the horizon, its centre 0.833° below it, the standard allowance for the air bending its light. Civil dusk is the sun 6° below, light enough to walk by. The golden hour begins with the sun 6° up.
The dates, to the minute
For every day of the year the sun’s altitude is worked out for this place, and the minute it crosses each line is found. A date is the first evening that falls after the hour you finish, and the last. When a clock change moves a date, the page says so, with the day the sun alone would have reached it.
Any place, any year
New York, London and Melbourne are worked out every night so their answers can be read before the page runs; the same arithmetic runs in your browser for any place, any year and any hour. Each city’s year is published beside its page as JSON, CC BY 4.0.
