Date

This sub-textual structure is used to represent when something occurs, including dates, partial-dates, and date-like-events:

• Fully specified dates: This includes data written out 'January 1st 2019' or abbreviates such as '01/01/2019'.
• Partial dates: More generally defined dates, where the day or month has been omitted, such as 'January 2019' or '2019'.
• Date-like-events: These are typically events used to signify when something occurred in the place of a specific date. Common examples may include '[since] our founding' or '[until] he retired'. Such events may also be used in conjunction with a more precise date, such as '[since] our founding in 2010'.

To help facilitate comparison, the information is standardized:

• Dates are standardized: Dates such as '1/1/18', '01/01/2018', '01-01-18', and 'January 1st 2018' all standardize the same. (Given our focus on US SEC filings, for numerical dates, a US-date ordering is assumed).
• Date-like-events likewise standardized: Similar to dates, date-like-events are standardized. For example, the underlying event of the firm-founding is captured the same, regardless of whether written as 'since our founding' or 'since we were founded'.
