Once in History
We’re not going to lie to you guys. This post actually had us thinking for a bit. If you use military time, at 8:20 and 20 seconds, it will be 20:20:20 in the year 2020. Apparently, this will only happen once in the history of the universe so, you know, cherish that one second or something?
The thing that the OP forgot is that there were 366 days in 2020. So, technically, 20:20:20 would appear 366 times throughout 2020. Now, if they claimed that it would only be 20:20:20 on the 20th of the 20th month in 2020… that would make even less sense.
