How the 9/80 cycle is mapped

Time Off Map treats the date on which a shift begins as its service date. Your selected known work date is matched to one position in the repeating sequence. Dates before and after that anchor are calculated in both directions, including leap days.

Before relying on the calendar

  • The cycle begins on Monday and places the regular day off on the second Friday.
  • Alternative 9/80 payroll-day splits are not represented in leave calculations.
Common questions

9/80 schedule questions

Can one known work date identify my entire calendar?

Only when you also identify where that date sits in the repeating cycle. Schedules with several work positions are ambiguous otherwise, so Time Off Map asks you to choose the matching cycle day instead of silently guessing.

Does a holiday automatically remove my shift?

No. Rotating operations frequently continue through holidays. Holidays are informational unless you deliberately turn on the setting that treats U.S. federal holidays as non-working days.

Why might my employer’s 9/80 schedule differ?

Schedule names are not universal standards. Relief times, fixed versus rotating shifts, Kelly or debit days, crew phases, and local agreements can change the sequence. Compare the visible preset with your roster before using the result.
