Slightly different. Dates like “10/10/10” repeat whole numbers- 10 repeated 3 times. However they contain more than a single digit value.
So “8/8/88” is “all 8’s” and we could say “10/10/10” is “all 10’s” but a ten is a one and a zero- so at the unit level it doesn’t repeat.
The format of single digit month or day omitting the zero before the digit is fine- humans generally omit non functional zeroes- if you count “8” apples it’s actually got infinite 0’s in front of the 8, add a decimal and you have infinite zeroes after the 8 as well- hence why we don’t generally write things like: “02.0+02.0=04.0” or “02.+02.=04.”
The year format omits century- we could call that a bit of a cheat since the year “88” is very different from the year “8888”
And “1988” contains 3 digit values. That said- human lives are such that generally when we speak in context about a lived event the century can be inferred- so much like our zero we can omit that information.
Thusly “8/8/88” and “10/10/10” CAN be part of the same pattern where that pattern is one of repeating sequence- but in a case where the pattern is a date created entirely using a single digit of the same value 11/11/11 is the only valid date on our Gregorian calendar that has a two digit month.
So “8/8/88” is “all 8’s” and we could say “10/10/10” is “all 10’s” but a ten is a one and a zero- so at the unit level it doesn’t repeat.
