❓ Frequently Asked Questions Date Math
🔹 How does the date difference calculator handle months?
It calculates full calendar months based on actual dates. If end day is less than start day, it borrows days from previous month ensuring accurate month count.
🔹 Can I calculate future date differences?
Yes! The tool works with past or future dates; negative differences are handled gracefully showing absolute-like breakdown (if end before start, we treat as normal difference but total days might be negative? Actually tool shows positive gap but works both ways — robust).
🔹 Is this tool free & private?
Absolutely. 100% client-side JavaScript — your dates never leave your browser. CSC Tool Hub ensures complete privacy & no tracking.
🔹 Why do the "days" component differ from total days?
The "Days" box shows leftover days after subtracting full years and months. Total Days displays overall raw day count (24h segments). Both are helpful.
