Age in weeks is counted from the date of birth to today — September 10, 2026 here — and not from a rounded number of years. Someone whose 30th birthday is today was born on September 10, 1996 and has lived 10,957 days, which is 1,565 weeks. Weeks are whole 7-day weeks since the birth date; the leftover days are shown as well, because 52 weeks is 364 days and a year is not a whole number of weeks.
