yyyymmddlike
The term "yyyymmddlike" refers to a pattern or format that resembles a date expressed in the ISO 8601 standard. This standard dictates that dates are represented numerically with the year first, followed by the month, and then the day, without any separators. Thus, a yyyymmdd format would appear as a sequence of eight digits, such as 20231027 for October 27, 2023.
The "like" in yyyymmddlike suggests that a string or identifier possesses characteristics similar to this date
