Gpt thinks 2025 is a leap year

I’ve been using gpt for work which often involves using dates and ive noticed that gpt thinks that ‘29/02/2025’ is a real date, so when im asking it to list dates in the future for a sheet ‘ie. from x date to x date every x number of days’ the data will be incorrect after 29/02/2025
its easy enough to just ask gpt to correct this, but you’ll have to do this in every new chat.
just thought i’d flag this!
