Sunlight Exposure Calculator

Estimate whether a garden spot gets full sun, partial sun, partial shade, or full shade based on daily sunlight hours.

How to measure sunlight

Check the spot several times in one day and add up the hours where direct sunlight reaches the planting area. Morning sun is gentler, while afternoon sun is usually hotter and stronger.

Gardening note

Sun exposure changes by season, nearby trees, fences, buildings, and sun angle. Recheck your garden spot during spring, summer, and fall for the most accurate planting decisions.
