Quay For Age Calculate & Round

Dear All

Thanks to note I would like to calculate the age as of today but with rounding up if the age is reached number of months 6
In addition to calculate how many days is remaining to reach the next rounding up

Example
Birth Date 01-Oct-2000 current age is 17 year and 5 months , so it is considered 17 year with remaining days for next rounding is 15 day
Birth Date 01-Sep-2000 current age is 17 year and 6 months, so it is considered 18 year with remaining days for next rounding is 181 day

Regards
