Formatted date/time and/or coded place of creation, capture, recording, filming, execution, or broadcast associated with an event or the finding of a naturally occurring object. This information in textual form is contained in field 518 (Date/Time and Place of an Event Note).
First Indicator - Type of date in subfield $a
Type of date information contained in subfield $a.
No date information is given and therefore, there is no subfield $a.
Date information consists of a single date, regardless of whether its form is year-month-day, year-month, or year alone.
Date information consists of more than one single date. Also used for two consecutive dates.
Used, for example, when the period of capture, execution, etc., spanned more than two consecutive days, and the individual dates are unknown or too numerous to be specified.
Second Indicator - Type of event
Specifies the type of event information found in the field.
Pertains to the recording of sound, the filming of visual images, the making or producing of an item, or other form of creation of an item.
Pertains to the broadcasting (i.e., transmission) or re-broadcasting of sound or visual images.
Pertains to the finding of a naturally occurring object.
$a - Formatted date/time
Seventeen characters, recorded in the pattern yyyymmddhhmm+-hmm, that indicate the actual or approximate date (yyyymmdd)/time (hhmm) of capture, finding, or broadcast and Time Differential Factor (+-hhmm) information. A hyphen (-) is used for unknown digits in the year/month/day segment. Within each segment, the data is right justified and any unused position contains a zero.
The first eight characters yyyymmdd (4 for the year, 2 for the month, and 2 for the day) represent the date and are mandatory if the subfield is used.
The following four characters, hhmm (2 for the hour, 2 for the minute), represent the time as hour and minute.
The last 5 character positions +hhmm give the Time Differential Factor information. The Time Differential Factor (TDF) is preceded by a plus (+) or minus (-) sign, indicating the hours and minutes the local time is ahead of or behind Universal Time (Greenwich Mean Time), respectively. Local times throughout the world vary from Universal Time by as much as -1200 (west of the Greenwich Meridian) and by as much as +1300 hours (east of the Greenwich Meridian).
For the hour, in all cases, the 24-hour clock (00-23) is used.
Multiple single date/times and date/times in a range associated with the same type of event may be contained in repeating $a subfields, with earlier times preceding later ones.

$b - Geographic classification area code
Four to six character numeric code for the main geographic area associated with an item. The code consists of the appropriate classification number from the range G3190-G9980 derived from the Library of Congress Classification--Class G by dropping the letter G.
Library of Congress maintains the Library of Congress Classification--Class G. Subfield $b may be repeated when more than one place is associated with an item.

$c - Geographic classification subarea code
Alphanumeric Cutter number for a geographic subarea, derived from the Library of Congress Classification-Class G or expanded Cutter number lists for place names. Cutter numbers for places in the United States are also published in Geographic Cutters. Class G, Geographic Cutters, and the expanded Cutter lists are maintained by the Library of Congress.
Each geographic subarea code is contained in a separate subfield $c. Subfield $c may be repeated when more than one place is associated with an item; each subfield $c must follow its associated subfield $b.
