This calculator also has date calculation keys for quick date calculations.

The "none" key will set the formating to "none" as a way to view the YYYYMMDD without commas. The "dec" key will return the formatting to decimal.

### 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.
