Age Calculator works out your exact age from a date of birth, then keeps every birthday and anniversary you care about in one place and reminds you before each one arrives. Enter a date and you get the full breakdown straight away: years, months and days, plus total days, weeks and months lived. You can check an age on any date you like, past or future, not just today, and save as many people as you want so the dates repeat every year on their own.

Here are just a few of the great features of Age Calculator:

• Exact age, on any date: years, months, days, hours and minutes — and the same calculation against any date you pick, not only today.
• Birthday and anniversary reminders: save birthdays, marriage days, work dates and personal milestones, and get a reminder before each one. Saved dates repeat every year automatically.
• Baby age tracker: a baby’s age in weeks, months and days, updated daily — the format vaccination schedules, clinic visits and admission forms actually ask for. More than one child can be tracked separately.
• Birthday countdown: days, hours and minutes until the next birthday, for anyone you have saved rather than just yourself.
• Date difference checker: the gap between any two dates in days, weeks, months or years — useful for an exam, a due date, a deadline, or the age gap between two people.
• Greeting templates: birthday and anniversary messages ready to send, so the reminder and the wish arrive together.

One place for every date you are tired of forgetting. Download Age Calculator and set your reminders once.
