On 2/13/26, I came to the realization that that particular date was a “*=” date. That is, 2 times 13 equals 26. While there aren’t any others this year (the other was 1/26/26), I was curious how many there have been this century so far, so I wrote a quick Python script to help me.

Something I find interesting is that out of the first fifty years of the century, only four years do not have times-equal days: ‘37, ‘41, ‘43, and ‘47. Intuitively this makes sense, since they’re prime numbers and our months cap out at 31 days.

When is or was your times-equal birthday? A ctrl+F-able list is provided here (or you could quickly calculate it). Let me know using #timesequalsbday on Bluesky ^_^
