Frequently Asked Questions (FAQ)
How does the calculator handle different month lengths and leap years?
The calculator automatically uses high-precision native temporal algorithms that respect leap years (including February 29th) and varying month lengths (28, 29, 30, or 31 days) without any approximation errors.
Does it use my local device timezone?
Yes! Calculations occur 100% locally in your web browser using your device's exact local timezone and daylight saving settings. No data is ever sent to an external server.
Can I calculate from a custom starting date instead of current moment?
Yes! Simply check the box "Calculate from Custom Starting Date & Time" at the top to select any historical or future base timestamp.
