Square Dates
Each year when I get my new diary, I like to look at the dates to see if they have any interesting properties. When I looked at this year's diary, I was pleased to find two dates that are 'square' in the following way. If the date is expressed with one or two digits for the day (ie, no leading zero is allowed), followed by two digits for the month and then the year in full, then 1.09.2025 is a square date, since 1092025 is the square of 1045.
The only other square date this year is 27.09.2025, since 27092025 is the square of 5205.
Using the same method of expressing the date, what is the first square date after 2025?
