Common Birthday Age Questions

Enter your date of birth in the calculator above. We'll compute the difference between your birth date and the current date, accounting for leap years and month lengths.
Why does my age in months vary?
Months have different numbers of days (28-31), so age in months can appear slightly different depending on when you calculate. Our tool uses precise date arithmetic.
How accurate is the heartbeat count?
The heartbeat and breath statistics are estimates based on average rates (72 BPM for heartbeats, 16 per minute for breaths). Actual numbers vary based on activity level and health.
