Meanwhile over at the Chart Harmony Discord…
The question of how we handle leap year birthdays (people born on February 29th, a date that only shows up in our calendar every 4 years) came up. Here’s my take.
What we celebrate astrologically is the solar return. For example, Keith’s birthday is March 3rd. His solar return, however, is TONIGHT! 
So, there is no “skipped day” when we focus on a solar return. The Sun will always reach the exact same degree in Pisces, and THAT is when the birthday/solar return is celebrated, not on a particular DATE.
That means, quite literally, the person born on February 29th has a birthday that — astrologically — going to be on the 28th sometimes, on the 1st sometimes, and of course in leap years, on the 29th sometimes (like, sometimes even when there IS a 29th… their solar return could be on the 28th or 1st!!!).
How’s that for an incredibly Mutable answer for an incredibly Mutable sign celebrating its incredibly Mutable birthday?
