Gedcom Standards generally use only these terms;
DATE_APPROXIMATED: = {Size=4:35}
[
ABT <DATE> |
CAL <DATE> |
EST <DATE>
]
Where :
ABT =About, meaning the date is not exact.
CAL =Calculated mathematically, for example, from an event date and age.
EST =Estimated based on an algorithm using some other event date.
DATE_PERIOD: = {Size=7:35}
[
FROM <DATE> |
TO <DATE> |
FROM <DATE> TO <DATE>
]
Where:DATE>
FROM =Indicates the beginning of a happening or state.
TO =Indicates the ending of a happening or state.
DATE_PHRASE: = {Size=1:35}
(<TEXT>)
Any statement offered as a date when the year is not recognizable to a date
parser, but which gives information about when an event occurred. The date
phrase is enclosed in matching parentheses.
DATE_RANGE: = {Size=8:35}
[
BEF <DATE> |
AFT <DATE> |
BET <DATE> AND <DATE>
]
Where :
AFT =Event happened after the given date.
BEF =Event happened before the given date.
BET =Event happened some time between date 1 AND date 2. For example, bet
1904 and 1915 indicates that the event state (perhaps a single day) existed
somewhere between 1904 and 1915 inclusive.
The date range differs from the date period in that the date range is an
estimate that an event happened on a single date somewhere in the date
range specified.
