Damn! I wrote a cheque yesterday. I'm just so unaware.
And today is also palindromic in the preferred format in China, yyyy.mm.dd.

This was prompted by the less than well-informed discussion of palindromic dates on 5Live a moment ago when they remarked on the birthday of one of the people in quarantine in Birkenhead after leaving Wuhan
According to the BBC Radio 4 news bulletin this AM, today is day 33 of 2020.

As this is a Leap Year, that means there are 333 days to go.

Of course, this will occur every leap year.
02.02.2020 is also the day 33 of the year and there are 333 days left in this year.
Dates palindromic in both dd.mm.yyyy and mm.dd.yyyy formats are structured ab.ab.baba, so must also be palindromic in the yyyy.mm.dd format.
theres a time & date palindrome, in 18 days, namely 02:02 20.02.2020
I'm glad the Chinese format has been mentioned. That format should be adopted universally, because it is unambiguous and obviously recognisable as a date. It also sorts properly when used as part of a filename.
I remember waiting to see 20.02 on 20.02.2002 to show in the display on my VCR!
The Chinese format mentioned above complies with international standard ISO8601. Certainly useful for sorting filenames etc, but I fear that dating systems are too culturally entrenched for them to be changed easily.
Please just stop
Even rarer than being palindromic is that today's date contains only two different digits.

That only happens twelve times this century.
Re. 11.11.1111: I had thought that even people in Europe wouldn't have written it that way, but a Wikipedia search reveals that Hindu-Arabic numerals were known in Europe by the 10th century. Of course, they may not have been used to write dates then.

Are there any future instances of two palindromic dates (1.11 and 11.1 1111)in the same month in both DMY and MDY systems? (and four in a year, along with 1.1 and 11.1) Given that there is no 22nd, 33rd etc month, it probably can't happen in the next eight millennia, but what about after that?
I have always used YYYYMMDD within computer file naming without realising it's the Chinese format in general life. How very practical of them. The 6-digit UK and US formats will require a double-take to avoid misunderstandings for another 12 years, after which it will be ok again.
I would have to break the habit of a lifetime to write a cheque today, As far as I am concerned it is the 2nd February 2020
As someone who is a big fan of patterns, I approve of this blog post.
I wonder why civilisations in the territory of the modern day USA never developed writing. I would think it would have spread from Central America (along with a calendar).
The "normal" way of expressing the date in this country is DD-MM-YY.
Using this format 20-11-02 will be the second of another raft of palindromic dates this century.
It's great to see your subsequent mention of the two digit aspect, which I find at least as interesting. This also opens up various HHMM and HHMMSS scenarios on each day, with about twenty minutes to go for the last ones today.

Incidentally, this (leap) year, July 20th (an amusing coincidence) will be 2020202 in YYYYDDD format.
International civil aviation uses DDD NN MMM YY (no spaces, always in capitals) as the recognised format for messages and reservations, rarely using the day name. So today in 'AirImp' code is [SUN]02FEB20. Date formatting doesn't only depend on cultures!

(and the Americans still use month-date in their airline reservations systems)
