Purists will say that this only happens once in a millennium. This Sunday, February 2, 2020 is a palindrome date if we write it in numbers. On the condition of entering a zero before the two of the day, 02 02 2020 can be read identically in both directions.
In teaching, a palindrome is a word or a group of words which can be read from left to right or from right to left. The classic examples are the cities of Laval and Noyon, the verb "ressasser" or the phrase "Aesop is here and is resting".
The last time a palindrome day took place was eight years ago, on February 21, 2012 (21022012). The next will be much closer, on February 12, 2021.
The last perfect palindrome day was in… 1111
But if we are looking for a perfect palindrome, that is to say valid whatever the calendar system (the Anglo-Saxons use the month / day / year formula), worldwide, the phenomenon is more rare. We must indeed go back to November 11, 1111 to find it. What happened in the world that day? Very clever that could be as precise.
On social networks, this curiosity in any case amuses a lot, and in many languages. Some have even taken care to note that this Sunday is also the 33rd day of the year, and that there are therefore 333 left to complete the leap year.
