Finding 18 years-old birthday

[Kenneth Chow]

Is there a function to find the 18th birthday of a person? Thx.

 

[m1_ru]

/*
replace today by date of the birth
*/
display
date( month(today), day(today), year(today) + 18) format "99/99/9999"
.
pause .

This logic has problem when the birthday is 2/29/2000.

 

[m1_ru]

/* sorry i really forget about those people */
/* that have one birthday during four years */
/* may be this will be good enough */
/* but it will return the same date */
/* for 02/29/2000 and 03/01/2000 */
display
date( month(v-date), 1, year(v-date) + 18) + day(v-date) - 1 format "99/99/9999"
.

It is a business decision, not a programming decision, on how to handle people born on Feb. 29th.

mr_1u has decided they have to wait until March 1st to be 18, but that may not be what the user wants.
