Tips: Enter your exact birth date for best results. Including your birth time will make the calculation even more precise. The calculator automatically uses the current time when you click "Calculate".
Q1: How accurate is this calculation?
A: Extremely accurate, down to the second when you perform the calculation.
Q2: What if I don't know my exact birth time?
A: The calculator will use midnight (00:00) as default, which still provides a good estimate.
Q3: Does this account for leap seconds?
A: Unix timestamps don't account for leap seconds, so the calculation may be off by a few seconds over a lifetime.
Q4: Can I calculate seconds alive for a future date?
A: No, this calculator only works for dates in the past up to the current moment.
Q5: What's the maximum number of seconds this can calculate?
A: The calculator can handle dates from 1901 to 2038 on most systems (Unix timestamp limitations).
