DATE literal allows you to specify a date constant using a string in 'YYYY-MM-DD' format. Then you can use this date value in any expression that expects a DATE data type.

Examples:

DATE '2014-12-20'
DATE '2014-12-20' + 1    -- Result: 2014-12-21 of type DATE
DATE '2014-12-20' - 1    --         2014-12-19
