Timeline
See today's sky, calendar position, and TEC reference point in one place.
Powered by TECNew here? This page shows today's date across multiple systems at once. The TEC framework gives every day a unique position on a timeline stretching back to the start of the Holocene geological epoch (about 11,700 years ago). Inside TEC, the H-CLET calendar tracks time using both the Moon (months) and the Sun (years) — unlike our usual Gregorian calendar which follows only the Sun. Look for the icons throughout to learn what each term means.

ℹWhy Systems Differ
Tropical astrology anchors the zodiac to the seasons. Sidereal astrology references the fixed stars and accounts for precession .IAU constellations use modern astronomical boundaries. TEC gives TriSky one chronological reference point for comparing all three.
