Seems to be a nice idea for calendar.
But it doesn't seems to work.
This example return a 22 in grey color.
Should I miss something?
Do you have a simple example to download?
Could I have more details about the parameters?
Thanks

The documentation included in the full fnCalendar function provides the instructions you'll need. Please email me with any questions.

Doesn't work; all but first cell empty.
Missing extend()?
1.5 worked OK.

If you're using the global calculation option, you'll need (1) to use the date as a trigger field and (2) the Extend function as noted in Step 3a in the documentation:
Let (
trigger = CAL::Date_G ;
fnCalendar ( Extend ( <date field> ) ; "calendar" ; 1 ; "" ; "" )
)
