Hi Andrew,
See this related emails from Markus


.....
The d2:yearsBetween() is not yet supported in the server side aggregation
of program indicators. For now you would have to use d2:daysBetween() / 365
- which is not 100% correct as the leap years is not considered. You wrote
d2daysBetween in your mail below(without the colon between d2 and
daysBetween), but i assume that was a typo in the mail.
If you used the expression
*d2:daysBetween(A{yourDateOfBirthAttributeUID},V{event_date})
/ 365* that should work fine on both the server and client side. Let me
know if this was the expression you tried. Note that the attribute UID
should be prefixed with A.

In the dev instance the example indicators on the MNCH / PHC program use
the V{event_date} as basis for the age calculation. This causes the
indicators to be calculated to NaN until you enter an event date. If you do
not explicitly want the age at the event, you can use V{enrollment_date}
instead.

Markus

P.S. The attributes of type date is not shown in the expression part of the
Program Indicator UI, only in the filter further down. This is all getting
reworked and sorted out soon, but as a workaround for avoiding typos you
can add the attribute in the filter part of the UI then cut'n'paste.
