To convert the dates to strings one uses the function TO_CHAR (date_string, format_string). PL/SQL also supports the use of ANSI date and interval literals. [11] The following clause gives an 18-month range:
<noinclude>[[Category:Date conversion templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character. Pages in category "Date conversion templates"

All examples use example date 2021-03-31 / 2021 March 31 / 31 March 2021 / March 31, 2021 – except where a single-digit day is illustrated. Basic components of a calendar date for the most common calendar systems: D – day; M – month; Y – year; Specific formats for the basic components: yy – two-digit year, e.g. 24; yyyy – four-digit ...
The last modification date stamp (and with DELWATCH 2.0+ also the file deletion date stamp, and since DOS 7.0+ optionally also the last access date stamp and creation date stamp), are stored in the directory entry with the year represented as an unsigned seven bit number (0–127), relative to 1980, and thereby unable to indicate any dates in ...
Using a signed 64-bit value introduces a new wraparound date that is over twenty times greater than the estimated age of the universe: approximately 292 billion years from now. [11] The ability to make computations on dates is limited by the fact that tm_year uses a signed 32-bit integer value starting at 1900 for the year. This limits the year ...
A precise date is specified by the ISO week-numbering year in the format YYYY, a week number in the format ww prefixed by the letter 'W', and the weekday number, a digit d from 1 through 7, beginning with Monday and ending with Sunday.
Date windowing is a method by which dates with two-digit years are converted to and from dates with four-digit years. [1] The year at which the century changes is called the pivot year of the date window. [2] Date windowing was one of several techniques used to resolve the year 2000 problem in legacy computer systems. [3]
