Counting notes

Which day should I enter?: Enter the day a form or a deadline asks about. The calculator uses that day as you typed it. It does not pick a rule for you.
Does the birthday rule change?: No. A 29 February birthday is still observed on 28 February in a year that has no 29 February.
Can the date be in the future?: Yes, as long as it is on or after the date of birth. The count is the age that person will have reached on that day.
