Some subexpressions can contain ranges or lists

For example: the subexpression (day (week)) can be "MON-FRI", "MON,WED,FRI", "MON-WED,SAT"

"": characters represent all possible values

Therefore, "" represents the meaning of each month in the subexpression (month), and "*" represents each day of the week in the subexpression (day (week)).

"/": characters are used to specify the increment of a numeric value

For example, in the sub-expression (minutes), "0Universe 15" means starting at the 0th minute, every 15 minutes.

"3x20" in the subexpression (minutes) means every 20 minutes starting from the 3rd minute (it has the same meaning as "3gamet 235,43").

"?" The character is only used in two subexpressions, day (month) and day (week), to indicate that no value is specified

When one of the two subexpressions is assigned a value, to avoid conflicts, you need to set the value of the other subexpression to "?"

"L": the character is only used in the day (month) and day (week) subexpressions. It is the abbreviation of the word "last".

But it has different meanings in the two subexpressions.

In the day (month) subexpression, "L" represents the last day of the month

In the day (week) self expression, "L" indicates the last day of the week, that is, SAT.

If there is a specific content before "L", it has other meanings.

For example, "6L" means the penultimate day of the month, and "FRIL" means the last Friday of the month.

Note: do not specify a list or range when using the "L" parameter, as this can cause problems
