Today I learned there’s a calendar created by an astronomer called the Hank-Henry Permanent Calendar that is identical every year.

  • Every 5-6 years there’s a 1-week Mini-Month
  • The extra month brings the 🗓 into sync with seasonal changes due to the 🌎 orbit.
  • No need to arrange 📆 each year. Do it once, and it is done forevermore.
