Enter the last date on which the record group, collection, or series was created, maintained, or accumulated by the creator.
For preliminary descriptions, Inclusive End Date may fall outside the dates of the creating organization.
Inclusive Dates Versus Coverage Dates
Inclusive dates are those that comprise the time period during which the record group, collection, or series was created, maintained, accumulated as a unified filing system by the creator because of some relationship arising out of the records creation, receipt, or use. Coverage dates are those that comprise the subject time period covered by the record group, collection, or archival materials. Normally, the subject dates are the same as the inclusive dates. However, if the dates are different, use the coverage dates as appropriate.
Active Accretions
If accretions to the record group, collection, or archival materials are still being sent to NARA, Inclusive Start Date and Inclusive End Date should define the time span for which the repository has holdings. For record groups, collections, or series that have yearly accretions, update Inclusive End Date when the accretion is accessioned.
Unknown Date
If you do not know the dates of a record group, collection, or series, estimate the century in which the record group, collection, or series was created. Enter the first year of the century (1700) in Inclusive Start Date, enter the last year of the century (1799) in Inclusive End Date, and use the "?" in Inclusive Start Date Qualifier and Inclusive End Date Qualifier.
For donated materials, estimate the dates based on the person or organization that created the materials. If you know the birth and death dates of the Creating Individual or the establish and abolish dates of the Creating Organization, use those as Inclusive Start Date and Inclusive End Date. If the birth date or establish date is unknown, enter the first year of the century in which the collection or series was known to exist in the Inclusive Start Date. If the death date or abolish date is unknown, use the donation date as Inclusive End Date. In all cases, use the ca. qualifier to indicate uncertainty.
When the Date Span is Only One Date
If the date is a specific day (02/11/1969), month (02/1969), or year (1969), enter the date in Inclusive Start Date and then repeat the same specific date in Inclusive End Date.
When the Date Span is One of Two Years
If the date is one of two years (1953 or 1954), then enter the first year (1953) in Inclusive Start Date, enter the second year (1954) in Inclusive End Date, and use the "ca." in Inclusive Start Date Qualifier and Inclusive End Date Qualifier.
When the Date Span is Several Years
If the dates fall between several years (1826-1835), then enter the earliest possible date (1826) in Inclusive Start Date, enter the latest possible date (1835) in Inclusive End Date, and use the "ca." in Inclusive Start Date Qualifier and Inclusive End Date Qualifier.
When the Date Span is a Decade
When describing a decade as a date span, enter the first year of the decade (1920) in Inclusive Start Date, enter the last year of the decade (1929) in Inclusive End Date, and use the "ca." in Inclusive Start Date Qualifier and Inclusive End Date Qualifier.
When the Date Span is a Century
When describing a century as a date span, enter the first year of the century (1700) in Inclusive Start Date, enter the last year of the century (1799) in Inclusive End Date, and use the "ca." in Inclusive Start Date Qualifier and Inclusive End Date Qualifier.
Date Form
Enter the date in MM/DD/YYYY form.
If the day is unknown, enter the month and year in the MM/YYYY form.
If the month is unknown, enter the year in the YYYY form.
Do not use 00 as a month or day.
Multiple Dates
If multiple date elements are used in a description at the Record Group, Collection, or Series Level, explain the distinctions in Date Note. For example, if a series has both inclusive dates and coverage dates, then explain the different dates in Date Note. At the File Unit and Item Level, it is not necessary to explain the distinctions between multiple date elements.
