How much sunshine have you lived through?
Add the places you've lived and the years you lived there. Each place carries its measured annual sunshine hours — satellite-era climate normals (NASA POWER, 2001–2020), the same figures behind every page on this site — and together they add up to your life in sunshine.
How it works
Type a city and pick it from the list — the atlas covers 3,798 destinations, every one with its own airport, so if your town isn't on it, choose the nearest listed city; annual sunshine changes slowly with distance at that scale. Leave "To" empty for a place you still live in. Years covered by two places at once are split evenly between them.
The total multiplies each place's annual bright-sunshine hours by your years there. Those figures are long-term climate normals — the average year, not a weather archive — so a 1988 winter in Oslo counts as Oslo's typical year, not the actual 1988 one. Everything runs in your browser: your places and years go no further than the page's own URL, which is what the share link reproduces. The method behind the numbers is on the methodology page, and the full dataset is free to download (CC BY 4.0).
