When Auto is clicked, this program automatically switches the screen between Day and Night settings as the sun rises and sets.
The program can use three different methods to establish the times of sunrise and sunset. You choose the method by entering or not entering information on Auto Settings.
1. If you do nothing — if you leave Auto settings blank — Blueless will assume that the sun rises at 6 am and sets at 6 pm. This is what happens all year round at the equator, and since humans evolved until recently in the tropics, this is probably the most natural schedule for our bodies. We can think of this schedule as a sort of paleo diet made of light instead of food.
2. If you want the program to use the actual times when the sun sets and rises at your location, you have to enter your latitude and longitude and leave the overrides blank. For more info, click the question mark next to Latitude and Longitude on Auto Settings.
3. If you want to specify the times when Blueless switches between day and night, enter the times in Sunrise Override and Sunset Override. The idea is that that you’re “overriding” the sun. For example, maybe you live in a place where days are short in winter and you want a longer period of simulated daylight than the sun provides. If so, you might enter 5:00 am and 7:00 pm as overrides and get fourteen hours of daylight settings each day. For more info, click the question mark next to the override fields on Auto settings.
The program uses these three options only when Auto is clicked.
