Easily to compare and sort with a simple string comparison
Understandable regardless of the national language
Cannot be confused with other common date representations
Corresponds with the standard 24-hour time system in which the larger units (hours) are also placed in front of small units (minutes and seconds)
Strings that contain a date followed by a time are also easy to compare and sort (e.g. “2019-09-07 20:15:00”)
Notation is concise and has a constant length, simplifying keyboard entry and table layout
Identical to Chinese date notation, meaning the largest cultural group (>25%) in the world is already familiar with the system
Date values with the order “year, month, day” are also widespread, such as in Japan, Korea, Hungary, Sweden, Finland, Denmark, and some other countries
A four-digit year format does not lead to any problems at the turn of a century
