Enter your date of birth to find your exact age and birthday countdown
Enter your date of birth and the calculator instantly shows your exact age in years, months and days. You can also change the "Age At Date" field to calculate how old you were or will be on any specific date — useful for legal documents, insurance forms or historical research.
Knowing your age in days can be surprisingly useful. Many people celebrate milestones like their 10,000th day alive (approximately age 27 years and 4 months). Insurance policies, legal documents and medical records often reference age in days for precision. Newborn care is always tracked in days during the critical first weeks of life.
The Date Difference tab calculates the exact time between any two dates — not just from birth to today. Use it to find how long you have been married, how many days until an event, the duration of a project, or the time between any two historical dates.
