Gaea is a personal timepiece and life-time keeping device based on Earth's orbital period. It indicates years, months, days and current time in Gaea format.
Gaea calendar starts with your birth timestamp in Gregorean format and moves in sync with the Earth from then. Each day corresponds to 1 angular degree around the Sun.
A year has 12 months, 30 days each and as such, doesn't respect Gregorean calendar days and is out of phase with day/night cycles.
There are no hours or minutes in Gaea, a day lasts 360 units, which is equal to 87661536 milliseconds.
Year index is zero-based.
