Thanks Lars,
I came to find an expression in indicators that does this in tracker:
like 40 - d2:weeksBetween(mother visit LMP, Current date)
The above gives the count down of the weeks remaining for the mother to deliver since the delivery has approximately 40 weeks.
Another expression was to display the age of the child for each visit to guide the nutritionist:
d2:monthsBetween(Child Birth date, current date)
The above gives the current months based on the date of visit.

 Hi Andrew,
how are you doing? First of all, would you mind asking this on the dev list? There are more people who can help you there.
Also it would be good if you could elaborate a bit about what you need to do regarding date conversion. Is the problem that you are asking beneficiaries about their age in months, and that you later would like to do aggregation based on months/quarters in dhis analytics apps?
best regards,
Lars

Dear All,
We are developing the case based nutrition system [Using DHIS2] that is targeting to track Pregnant Women, Lactating and Children under 2years.What we are tracking is Attributes and tracker variables like Date of Birth, hight, weight, LMP Date and We would like to Display on our program dashboard the indicators like BMI, Height for Age, Weight for Age and also expected deliveries using the LMP dates which is our data element that is set to date type. 
Is there anyone who knows how to convert the dates into Months or years without use of coding, i mean during the calculation of Program indicators? . We also need users to enter the date of Birth of a Baby or Mother and the system popup the Age in months or Years.
