How to describe time periods
Dates
Dates are specified within
Time_Period_Information.
- A single day
Single_Date/Time:
Calendar_Date: A year or day
- A discrete set of days
Multiple_Dates/Times:
Calendar_Date: A year or day
Calendar_Date: Another year or day
Calendar_Date: more if needed...
- A range of days
Range_of_Dates/Times:
Beginning_Date: Starting year or day
Ending_Date: Ending year or day
The dates should be written like YYYY (a four-digit year) if you only know
the year, or YYYYMMDD (where MM is the month 1-12 and DD the day 1-31) if
you know the day.
Times
You can add times too, but don't unless you really need to be
that precise. Write the times as HHMM or HHMMSS (HH is hour 0-24, MM
minutes 0-59, SS seconds 0-59):
Single_Date/Time:
Calendar_Date: A year or day
Time_of_Day: Time as HHMM or HHMMSS
Range_of_Dates/Times:
Beginning_Date: Starting year or day
Beginning_Time: Time as HHMM or HHMMSS
Ending_Date: Ending year or day
Ending_Time: Time as HHMM or HHMMSS
