Date and time notation in South Africa
South Africa signed up to use ISO 8601 for date and time representation through national standard ARP 010:1989 in 1998. The most recent South African Bureau of Standards standard SANS 8601:2009 "... is the identical implementation of ISO 8601:2004, and is adopted with the permission of the International Organization for Standardization" and was reviewed in 2016.
Date
Even so, the old date format is still commonly used in the format "dd/mm/yyyy", with the "day month year" order being more common with non-numeric month designations.
Sunday is the first day of week and Saturday is the last day of the week.[1] The first week of the year is the week that contains January 1st, the first day of the year.[2]
Time
"h" as time separator, is still common (e.g., 03h25 in place of 03:25), particularly when only the time is given.
