Date calculator FAQs
Is the date difference inclusive or exclusive of the end date?
The calculator measures the elapsed time between the two calendar dates you enter. The breakdown in years, months, and days is based purely on calendar math rather than including or excluding a specific day in a payroll or billing sense.
Can I use this tool for business days only?
This version works with calendar days and does not skip weekends or holidays. For business-day calculations you will need to manually account for non-working days or use a specialized business calendar tool.
Does the calculator adjust for time zones?
No. The tool operates on dates only and assumes both dates are in the same local time zone. For most planning, project, and personal use cases this is sufficient, but time‑zone–sensitive scheduling should be checked against a calendar that supports your specific region.
