Sunrise Time is a new app that enables you to explore your relationship with time. Simply choose how you spend your time and how much you are able to spend, and Sunrise Time will show you how much more productive and fulfilled you can be with greater self-control.
Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion is so convincing that many cultures had mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.

These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise. (Source:
“This is actually summer in the southern hemisphere. For our friends down south, this is actually the longest day [in that] it has the most hours of daylight. This is something that we cover in school, but because we don't talk about it very much, we don't think of it too often. And it's not really a whole day. It's really an instant. Of course, in prehistoric times, people had all kinds of mythology that was involved with certain rituals for fertility and for agriculture and a number of things.”
In late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.
