The angle of the sun is vital, which is affected by time of day, time of year, and your latitude. This is a chart showing time of day and year on the UV index, for a given latitude (NYC so about 41°N) https://www.grassrootshealth.net/wp-content/uploads/2019/05/... (PDF)

The rule of thumb I've heard is that you make vitamin D iff your shadow's height <= your height.
