# Date expressions

Functions that treat the databox value as a date: comparing it, shifting it, taking it apart, and formatting it for a message.

Use these rather than the comparison operators. `<` and `>` compare text, which happens to work for some date formats and silently fails for others; `After`, `Before` and `BetweenDates` compare dates.

Dates are read in UK format, and any time part is ignored when dates are compared.
