Get your exact age in years, months and days, plus your zodiac sign
Checking your access…
AllFreeTool is a free online age calculator that works out how old you are in years, months and days from a date of birth, and also counts the total days, weeks, hours and months you have been alive. It shows how many days remain until your next birthday, which age you will turn this year, and which zodiac sign your date falls under. Everything is computed locally and your date of birth is never stored or uploaded.
It is handy for form filling, for school and visa applications, for party planning, or simply for settling an argument about how old someone really is. You can also set a different reference date, so you can calculate an age as of any past or future moment rather than only today.

Common questions
How is the age in years and months calculated?＋
The tool counts whole calendar years, then the remaining months, then the remaining days, borrowing the length of the previous month when a day count would otherwise be negative. This is the same calendar convention people use for birthdays, so the result matches what you would say out loud.
What do the lifetime totals include?＋
You get the number of days, weeks, hours and months you have been alive since your date of birth, all derived from the same reference date used for the main age. These are useful for record-keeping and for fun comparisons, and they update whenever you change the reference date.
Can I calculate an age for a different day?＋
Yes. The reference date field lets you pick any day, past or future, and the calculator measures the age as of that moment. This is handy for official forms that ask for an age on a specific date, or for working out an age at a past event.
Is my date of birth sent anywhere?＋
No. The calculation happens entirely in your browser, and the tool states plainly that your date of birth is never stored or uploaded. There is no account to create and no form submission involved, so the information stays on your device.
