Frequently asked questions
Can this calculate business days?
This version focuses on calendar difference. For weekday-only counts, a dedicated business days calculator is usually better.
Why are month-based results sometimes tricky?
Months have different lengths, so some tools emphasize total days to avoid ambiguity. Calendar math can look different depending on the output format selected.
Can I use this for legal or contract deadlines?
You can use it for quick planning, but official deadlines should always be verified against the governing rule or document.
