A few weeks ago, I had a shower thought: I'm turning 33.33 years old this year. Exactly one-third of the way to 100! This got me thinking—what other interesting age milestones am I missing out on because I'm just waiting around for my regular birthday? So, I built Bonus Birthdays to find them. It calculates things like your 10,000th day, your 1-billionth second, and a bunch of curated pop-culture milestones. You can sync them to your calendar so you don't forget, and surprise your friends by congratulating them on their milestones! I’d love your feedback: - What is your next Bonus Birthday? - Are there any cool meme numbers or math milestones I should add to the list? Let's find an excuse to eat some cake today 🍰
