Frequently Asked Questions
Common questions regarding the age counter and business day calculations.
Q.How does the business day calculator handle custom weekends?
Unlike standard calculators which assume Saturday and Sunday weekends, this tool lets you select exactly which days are weekends (e.g., Friday and Saturday, Sunday only, etc.) via simple checkboxes, adapting to any regional or religious work schedule.
Q.How does the live-ticking age calculator work?
The live age calculator takes your exact birthdate and time, compares it to the current system time at a high refresh rate (60 times per second), and uses calendar math to render your age down to milliseconds instantly in the browser.
Q.Is it possible to add business days to a start date?
Yes! The Date Math module allows you to input a starting date, select "Add", enter a number of business days, and the engine will count forward, automatically skipping your selected weekend days and any custom holidays entered in the text field.
Q.Is my birth date stored anywhere?
No. The calculator runs completely in your device browser. We do not transmit or store any date or time inputs.
