A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (the Unix epoch). It's widely used in programming and databases because it's a simple integer that represents a unique point in time.
What is the ISO 8601 date format?
ISO 8601 is an international standard for date and time representation. For dates, it uses the format YYYY-MM-DD (e.g., 2026-07-11). This format is unambiguous and sorts correctly alphabetically, making it ideal for data exchange.
