Questions
How is exact age worked out?
The calculator counts whole years and months from the date of birth, then the days left over. A birthday on the 31st counts a month as complete on the last day of shorter months.
What about birthdays on 29 February?
In years that aren’t leap years, the birthday is counted on 28 February.
Can I use this for a school application?
Yes, to check an age. For school entry rules, the grade calculator tells you which year your child can start Grade R and Grade 1.
