How it works
Total days uses UTC midnight difference (avoids DST shifts). Calendar span shows full years, months, and remaining days using month boundaries.
Examples
2026-01-01 → 2026-08-26 = 237 days ≈ 33 weeks + 6 days

Leap days? Handled by the calendar; Feb 29 in a leap year counts as one day.
Working days? Not included — this is calendar days only.
