Upcoming August 11 and August 22 are double digit days, before new year of 2022.

Important number 6 and 8?

68 is the atomic number of erbium, a lanthanide. In the restaurant industry, 68 may be used as a code meaning "put back on the menu", being the opposite of 86 which means "remove from the menu". 68 may also be used as slang for oral sex, based on a play on words involving the number 69.

I guess I think too much!

Also, DOUBLE digits in the new year:

11/11/22 = 2.2.4

11/22/22 = 2.4.4

Don't get me started on 2/22/22 cause that's different.

I shall stop posting now.

That makes sense anon, thanks!

Digit '1' on a rotary phone is the shortest delay in processing that number, since the mechanical telephone device uses the fastest action.

So then… why not 111 back in the days?
