Off the top of my head, I can think of a few...
We had nine consecutive palindrome dates earlier this year. 2/20/22 through 2/28/22 (yr in '2 digit' mode).
We had a ten-day pattern in 2021 - starting with the date of the inauguration. 'Ten days of...?'
The inauguration date is a little 'extra special', in that it is a palindrome in both yr-4 AND yr-2 formats. (1/20/2021 and 1/20/21). That pattern happens once a year for nine consecutive years, starting on...the inauguration date. (1/20/2021, 2/20/2022, 3/20/2023, etc)
Palindrome dates are 'rare-ish', but 1/20/2021 has a few 'extras' that others don't.
<time passes...>
Ok, I wrote some code and found that there are 57 palindromic dates between 11/9/17 (the first time Q said 'Think Mirror') and today. (54 in m/d/yy, 4 in mm/dd/yy, 4 in m/d/yyyy, and 2 in mm/dd/yyyy)
Of those, only 7 dates are 'multi-palindromic', meaning they form palindromes in more than one date format.
These are 8/10/18, 9/10/19, 1/20/21, 12/2/21, 12/11/21, 12/22/21, and 2/20/22. They are all palindromic in the (given) m/d/yy format, and I'll leave it to you to find the other format for each. (Note: Only one of these multi's are palindromic in mm/dd/yyyy format.)
Happy hunting.
