Kelly days are periodic additional days off that vary by department. This example shows a base 24/48 cycle only; add your actual Kelly days as dated overrides, never assume a universal Kelly pattern.
Pick your platoon
Use a date from your department’s official calendar. ABC and ABCD are template assumptions, not department facts.
A Kelly day skips a scheduled tour without moving the rest of the cycle. Leave the Kelly date blank to see the base 24/48 schedule only.
Add one confirmed shift to line up your calendar.

Nationwide public holidays do not convert scheduled duty into time off. Regional holidays and employer rules may differ.
2027 pattern facts for Kelly day firefighter calendar
Using 1 Jan 2027 as the first duty date, this 1-on / 2-off illustration contains 243 rostered rest dates in 2027, with a longest uninterrupted rest stretch of 2 days inside the calendar year. That starting point is illustrative, not your employer’s published duty roster.
Across all 3 equally weighted possible starting phases, the entire 24–26 Dec Christmas period is free in 0 phases (0.0%); 31 Dec through 1 Jan is free in 1 phases (33.3%).
For illustrative summer-school intervals, the mean number of rostered rest dates is 28.0 of 42 dates for an Australian December–January example, 28.0 of 42 for a UK July–August example, and 41.3 of 62 for a US June–August example. These fixed windows are not official countrywide school calendars and do not include travel or approved leave.
Planning notes specific to Kelly day firefighter calendar
The term Kelly day describes additional scheduled time away from duty in some fire service systems, but departments do not use one universal Kelly calendar. A Kelly arrangement may be layered over a 24/48 base cycle to manage total working hours. The frequency, anchor and treatment of shifts differ by contract and station. This page deliberately begins with a transparent 24/48 example rather than inventing a supposedly standard Kelly interval.
If your department specifies every seventh, ninth or other recurring duty shift as a Kelly day, record the actual published dates and verify how the pattern restarts after an exception. A calendar day marked away from station is not automatically annual leave; Kelly time and approved vacation may be accounted for differently. The 2027 table therefore describes the base cycle only and must not be interpreted as a final count of a real firefighter’s duties.
Before sharing or subscribing to a Kelly-based roster, compare your first duty date and any rostered Kelly exceptions against your departmental schedule. Supervisors may issue yearly schedules that include trades, mandatory training and changes in relief coverage. Use explicit overrides for those exceptions. This is a date-planning aid, not a legal interpretation of shift-hour limits or collective bargaining rules.
Consider two departments that both call an additional relieved shift a Kelly day. One may use a fixed published annual sequence while another rotates the relieved duty day through a cycle. Their annual hours and which weekends become free may differ materially. The correct input is not a guessed universal Kelly formula but the station’s official Kelly-day list. If your duty schedule changes midyear, preserve the accurate anchor and enter the newly published exceptions rather than restarting every pattern on January first.
