"Date": "A precise calendar date (e.g. '1979-08-02').",
"DateAndTime": "A specific date and time with precision (e.g. '2004-01-01T10:10:10+05:00').",
"Interval": "A range of dates from one specific date to another (e.g. '1979-08-28/1979-09-25').",
"UncertainOrApproximate": "A date that is either uncertain or approximate or both, indicated with a question mark (?), tilde (~) or percentage (%), respectively (e.g. '1979-08-28~').",
"Unspecified": "A date where certain parts are unspecified, indicated with 'X' (e.g. '1979-08-XX').",
"Level1Interval": "A date interval where one or both dates may be uncertain or approximate (e.g. '1984-06-02?/2004-08-08~').",
"UnspecifiedIntervalSection": "An interval where one of the bounds is open-ended (indicated with a double-dot ..).",
"LongYear": "A year longer than four digits, used to indicate historical or far-future years (e.g. 'Y-12000' equates to 12000 years BCE)",
"Season": "A season instead of a month, identified using a non-month integer (e.g. '1979-22' equates to Summer 1979).",

"Level2Season": "A seasonal expression with further uncertainty specification, such as approximate seasons.",
"ExponentialYear": "A year in exponential notation, often used for very large or small years (e.g. 'Y-17E7' is estimated as -170000000."
