If you ask Siri how old you are, you may likely get an extra year tacked onto your actual age. But, only if you haven’t yet had your birthday this year. (If you haven’t added your birthdate to your iPhone contact card, Siri won’t be able to answer.)
I asked Siri my age this morning and was informed that I am… Well, never you mind what she said, but suffice it to say, the reported age was a year older than I actually am.
Dutch blog iCulture says the discrepancy likely relates to Siri miscalculating birthdays by only taking into account a person’s year of birth and not the month or day. As evidence of this, Siri displays the correct age for anyone with a birthday that has already passed this year.
MacRumors reports that users are saying that both iOS 15.3 and the iOS 15.4 beta users are seeing the incorrect age reporting issue.
While this is a minor flaw, it, unfortunately, adds to the bad reputation Siri has in some quarters.
