Why celebrate this?

Monumental progress

Our planet Earth, along with the rest of the Solar System travels around the galactic center of the MilkyWay Galaxy every 225 million Earth years.

One centi-arcsecond of this rotation is called a Galactic Tick. A Galactic Tick happens every 633.7 days, or 1.7361 years.

Galactic Tick Day is set aside to acknowledge our Sun's motion, our progress around the home galaxy, and to celebrate humanity's knowledge of this motion.

Origins

Honoring Awareness

The first Galactic Tick Day was one Galactic Tick (1.7361 years) after Hans Lippershey filed the patent for the first telescope on October 2nd, 1608.

This is in honour of the telescope's power to allow us to acheive awareness of the nature of the universe.

The 238th Galactic Tick Day is later this year on December 15th, 2021. Let’s celebrate together!
