Date Entry

CALC 1 uses the ISO 8601 YYYYMMDD format for entering dates. This is a common date format that most users around the world are familiar with.

For example, April 28, 2004 is entered as 40428. June 4, 2018 is entered as 180604.

Date Entry Shortcuts

If you omit the first two years (the century) of YYYY, CALC 1 will use the current century, 20. This is a common truncated representation.

If you omit the entire YYYY, CALC 1 will use the current year.
