Questions
How are months and days counted?
A month is complete when the same day of the month comes round again. For dates like the 31st, the last day of a shorter month counts.
What if I was born on 29 February?
In years without a 29 February, the birthday is counted on 28 February.
Can I check someone’s age on a past or future date?
Yes — change the “Age on” date, for example to check age on an exam or job-application cut-off date.
