About this app

D-Day & Age is a free countdown and age calculator — track the days until or since the dates that matter, and find out exactly how old you are. Birthdays, anniversaries, due dates, exams, trips, sobriety, a new job — see every important day at a glance and never lose count.

Add a date and the app instantly shows your D-Day: how many days are left (D-100) or how many have passed (D+30). The list sorts itself so the closest day is always on top.
