Prompt: list the next friday febuary 9ths occurring on leap years
Response: Unfortunately, there is no such thing as a Friday, February 9th occurring on a leap year. Here’s why:
• February only has 28 days in a typical year and 29 days in a leap year.
• Since a month consists of 4 weeks (28 days), the day of the week for any particular date repeats every 4 years.
• This means that if February 9th falls on a Friday in a non-leap year, it will fall on a Monday in the next year, Tuesday in the year after that, Wednesday in the third year, and back to Friday in the fourth year.
• However, since the fourth year is a leap year with an extra day in February, February 9th “shifts” by one day, falling on a Saturday instead of Friday. Therefore, it’s impossible for February 9th to be a Friday in a leap year. The next Friday, February 9th will occur in 2029, but it will be a common year, not a leap year.

did you know people born on leap years only emerge and exist on leap years?
They’re part cicada though, so there’s that.

Gemini Advanced (Ultra) gets it right:
I asked the same question to regular Gemini and got a seemingly correct answer as well.
Copilot nailed it
