Calculating Age for future dates

Calculating Age for future dates

Calculating Age for future dates



I have a list of children that may appear in different financial years and I need to work out their age based off this,
in the example below Child1 was born on 12 Feb 2008 and appears in 3 financial years.

Is there a way to calculate his next birthday based off Calc_Year and then therefore be able to calculate his age.

fin_year and calc_year are automatically pulled through in the query as the user selects a term on the form, i.e "spring 2011"
which on the table is associated with fin_year and calc_year

The only but I'm struggling with is the "next birthday in calc year".


CODE --> datasheet

Childsname	DOB	        fin_Year    calc_Year	Next Birthday in calc_Year	Age
Child1	        12-Feb-08	2010/11	    2010	12-Feb-10	                 2
Child1	        12-Feb-08	2011/12	    2011	12-Feb-11	                 3
Child1	        12-Feb-08	2012/13	    2012	12-Feb-12	                 4

What have you tried and what were the results?

Logic leads to evaluating if current is less than month & day then this year else next.

RE: Calculating Age for future dates


thanks for the reply but I worked it out in excel and then applied it to access, basically I calculated a few different fields in the query

I had to just show the year for the childs DOB


YR: Year([dteChildDOB]) 

then I had to calculate the difference between the calc_year and YR


YRDiff: [strCalc_year]-[YR] 

and finally had to add the YRDiff to the child's DOB to show the next birthdays in the financial years


NextBirthday: DateAdd("yyyy",+[YRDIFF],[dteChildDOB]) 

I should have thought about it more but thanks again

the output I get below is from the query which matches my example

CODE --> datasheet

Childsname	dteChildDOB	strFinancialYear	strCalc_year	YR	YRDiff	NextBirthday
Child1    	12-Feb-08	2010/11	                2010	       2008	2	12-Feb-10
Child1  	12-Feb-08	2011/12	                2011	       2008	3	12-Feb-11
Child1   	12-Feb-08	2011/12	                2011	       2008	3	12-Feb-11
Child1  	12-Feb-08	2012/13	                2012	       2008	4	12-Feb-12
