Frequently asked questions
Is this tool free?
Yes. Calchemy tools are free to use in your browser.
Is my data uploaded?
No. The tools are designed to run locally in your browser unless clearly stated otherwise.
Do I need to enter a time of birth?
No - if you leave it blank, the calculator assumes midnight. That's accurate for the years/months/days figure, but the hour, minute and second totals could then be off by up to a day. Enter your birth time for exact numbers.
How are the years, months and days calculated?
Using your actual calendar birth date, so it accounts for real month lengths and leap years rather than an average.
Why do the numbers keep changing?
The weeks, days, hours, minutes and seconds totals update live, once a second, for as long as the page stays open.
