Compute a date dimension

What is a Compute a date dimension ?

This kind of dimension enriches your card with data, like any other dimension. But the value on a card is not chosen manually in the card edition dialog, but is the result of a computation involving values provided by other dimensions on your card.

Example

Let's say that you have a number dimension called Due date, and you'd like to compute another date, e.g. 3 days before deadline. The formula might be the following:

_.due_date - P3D

The expression language

The expression language uses Elo, that can be used to compute any date you'd like. In those expressions:

• _ denotes the current card, on which the computed value applies,
• _.xxx denotes the card value along the dimension whose name is xxx (in snake_case format ; if your dimension is named Due date, the variable is due_date)
• NOW, TODAY are constants with obvious date & time semantics
• D2026-03-26 is a date literal
• SOD means Start Of Day ; EOD means End Of Day
• SOW/EOW, SOM/EOM, SOY/EOY can be used similarly for weeks, months and years
• Elo also supports durations, such as P1MT2H (1 month and 2 hours). Check the language reference.

How to find the dimension codes ?

In the formula editor, pressing _. should provide you with a suggestion showing the list of dimensions :

For a particular dimension, you'll find the code to use in formulas in the General panel when editing it :

• Starting with Klaro Cards 0.259.0, Klaro Cards uses Elo which is simple, clean and powerful. The documentation online is certainly worth a read.
• For business instances on earlier versions, Klaro Cards still uses the Livescript language.
