Sun Time Planner

Find out how long you can spend in the sun, per side, before you burn.

1 Your skin type

Optional: background hint

Only shown as a rough guide next to your quiz result. Your answers about how your skin reacts to sun matter far more.

2 Your current tan

A tan only adds a little protection (roughly SPF 2 to 4), so this changes the result modestly.

3 Sunscreen

Most people apply about a third of the amount used in lab tests, so we count sunscreen at one third of its label SPF.
