Your yard's light, finally visible
A sun map turns “I think that corner's kind of shady” into exact hours of direct sun — everywhere on your property.
Hours of direct sun, cell by cell
A rainbow grid over your yard, from deep purple (full shade) to red (10+ hours). Full sun is 6+ hours a day, part sun is about 3–6, and full shade is under 3 — and you can see at a glance which parts of your yard are which.
Real shadows from your house & trees
It casts the actual shadows your home and trees throw across the yard, so the shady strip along the fence shows up on the map before you waste a tomato bed on it.
How your light shifts with the seasons
Sun that floods the yard in July can vanish behind the house by October. Compare any two dates side by side, or see a single map averaged across your whole growing season.
What to plant where
Match sun-lovers to your reddest zones and shade-tolerant plants to the cool ones. The map takes the guesswork out of siting a garden bed, a fruit tree, or a native border.

How do I find out how much sun my yard gets?
Enter your address in the sun map above. We render a rainbow of direct-sunlight hours over a satellite photo of your yard, cell by cell, so you can see exactly which areas get full sun and which are shaded — free, no account.
What counts as full sun, part sun, and shade?
Full sun is 6+ hours of direct sun a day; part sun / part shade is about 3–6 hours; full shade is under 3. Your sun map shows which parts of your yard fall into each.
Is the sun map free?
Yes — no account, no credit card. Map your yard, compare dates, see a season average, and download your map for free.
How does the sun map calculate shade?
It models the sun's path for your exact coordinates through the day and year, then casts the shadows your house and trees throw across the yard — so it's real solar geometry, not a guess.
Do I need an account to use it?
No. Enter an address and your map renders instantly. You can optionally save it to your email to reopen it later on any device.
Is this a sunlight calculator?
It's a visual one. Instead of a single number, you get a map: every part of your yard colored by how many hours of direct sun it gets, plus tools to compare dates and watch shadows move.
