Avi-on calculates Sunrise/Sunset based on the geographic location of your devices at the BEGINNING of every month.
During the month, as the sun travels through the sky, the precise time of sunrise/sunset changes in your area. You will also experience sunrise/sunset differently depending on whether you are in the mountains or on the flat plains. Avi-on’s pretty smart, but we’re not smart enough to know that you live in a canyon.
When you pick a sunrise or sunset schedule, we calculate the sunrise/sunset times based on the location of your devices for every month. The device will automatically update to a new time every month.
