This is easier to read but not descriptive enough since there are different kinds year, month, day. Year can be 2 digits, 4 digits, regular or week year. Month can have leading zero or not, long name, short, name. Day could be Julian, leading zero or not, day of the week, etc

That's when you can be more precise if you want: `[year padding:zero repr:full base:calendar sign:automatic]`. The format is also checked on compile time.
