A full-year chart of sunrise, sunset, and day length for any place on Earth.
How this tool works
Pick a place and year, and the tool computes sunrise and sunset for all 365 days with standard NOAA solar equations, drawing the year as a chart: the solid line is sunrise, the dashed line sunset, and the space between them is daylight. The longest day, shortest day, and total swing are called out above the chart.
What you can do with it
- See the whole shape of your year of daylight at a glance
- Compare the brutal winter darkness of northern latitudes with the equator's flat 12-hour days
- Find the longest and shortest days for any year, past or future
- Watch polar day and polar night appear as gaps at high latitudes
Why use it
Day-by-day sunrise sites answer today; the year-shape is what actually explains seasonal mood, energy use, and why June evenings feel endless. One chart carries the whole story.
