How this is worked out

7 steps
  1. Start 2024-01-01 09:00 (Monday), end 2026-09-14 17:00 (Monday).
  2. Elapsed days = day number of 2026-09-14 minus day number of 2024-01-01 = 987.
  3. With the clock: 987 x 1440 + (1020 - 540) = 1421760 minute(s), so 987 whole day(s) and 8h 0m remain.
  4. Calendar walk with the day borrowed from the clock: 2 years, 8 months, 13 days, 8h 0m.
  5. 987 days = 141 week(s) and 0 day(s).
  6. Decimal years = 987 / 365.2425 (mean Gregorian year) = 2.7023.
  7. Business days 2024-01-01 to 2026-09-14 inclusive = 706 weekday(s) - 29 holiday(s) = 677.
