Estimate model
Exact date arithmetic can count values such as elapsed days and leap days. Approximate cycle counts use average lengths for seasons, lunar cycles or Earth orbits.
🌍 SINCE YOU WERE BORN
How much world-time has passed since you arrived?
Turn your lifetime into sunrises, seasons, leap days and lunar cycles.
Sunrises*
Seasons crossed*
New Years experienced
Leap days passed
Full moons*
Earth orbits completed*
*Sunrises, seasons, full moons and Earth orbits are approximate curiosity counters.

ASSUMPTIONS & INTERPRETATION
Since You Were Born
Translate elapsed lifetime into several perspectives: calendar-derived counts plus clearly labelled estimates for recurring natural cycles.
What the number means
Do not read every number with the same precision. EgoTools separates exact calendar outputs from “about” values based on averages.
Worked example
Thirty years is exactly a certain date interval for one birth date, but “about 120 seasons” is a perspective estimate rather than a log of astronomical boundaries crossed.
Good to know
Exact counts vs natural-cycle estimates →Natural cycles are not perfectly uniform and season naming depends on hemisphere, so approximate values are labelled accordingly.
