Select your favorite city, any month or year, and see a fairly accurate table of sunrise/sunset times for the location.
Is it accurate to figure the published times between sunset and sunrise as true dark time, or are there “fudge factors” you can share with readers?

Thanks for the information, Jimmy.
Growers will find this information useful when figuring the date that flowering is triggered.
At the beginning of summer, June 22, sunlight affects plants for only perhaps 10 minutes before sunrise and 10 minutes after sunset.
