The next minor palindrome date is on 22.7.22. This can only be found on the small date stamps in post offices that opens on Sundays (mall post offices).
As a quick guide, here are the other palindrome dates for the rest of the year:
22.8.22 (also minor ambigram)
22.9.22
22.11.22 (also minor ambigram)
As there are post offices that open 7 days a week and with a combination of different states, should be able to get most of them this year!
