M-I-R-R-O-R Birthday
The "Official" Certificate Text
The M-I-R-R-O-R Birthday (noun)
/ˈmɪrər ˈbɜ rθdeɪ/
1. A rare chronological phenomenon occurring only once or twice in a lifetime, when a mother's age and her child's age become perfect geometric and numerical reflections of each other when turned upside down.
2. Specifically defined as the Maternal Inverted Reverse Reflection & Offspring Relation Birthday.
* Example: "When Mom turned 89 and I turned 68, we celebrated our first M-I-R-R-O-R Birthday, knowing we get to flip the candles one more time when we hit 97 and 76!"

Title the post: What is a Maternal Reverse Digital Inverse / Upside Down Birthday called?
My mom turned 89 and I turned 68. The numbers flip perfectly upside down, so we invented a name for it: The M-I-R-R-O-R Birthday.
Body Text:
Yesterday (October 18), my mom and I realized our ages have reached a rare geometric and numerical milestone. If you flip her age (89) upside down, it perfectly matches my age (68).
Because there isn't an official traditional term for this, we decided to establish one:
The M-I-R-R-O-R Birthday
(Maternal Inverted Reverse Reflection & Offspring Relation)
We did the math and realized this only happens twice in our lifetimes. We get to celebrate our second one in 8 years when she hits 97 and I turn 76!
