24/48 Schedule: Firefighter Shift Calendar Guide + Free Generator

The 24/48 schedule is the backbone of fire service staffing across the country. Work a 24-hour shift, go home for 48 hours. Three teams, three days, repeat. The 24/48 schedule has been the standard in fire departments for decades, and for good reason: it’s simple, it provides reliable coverage, and firefighters get 2 full days off between every shift.

If you’re a firefighter, EMT, or paramedic starting on a 24/48 schedule rotation, this guide covers how the cycle works, what your hours look like, the real pros and cons, and how it compares to the Kelly schedule. There’s also a free 24/48 calendar generator so you can map out your 24/48 shifts for the year and sync them to your phone.

What Is a 24/48 Schedule?

The 24/48 schedule is a 3-day rotating shift pattern where you work one 24-hour shift followed by 48 hours (2 days) off. Three teams rotate through the 24/48 cycle so that one team is always on duty. It’s the most common firefighter shift schedule in the United States, and the 24/48 schedule remains the go-to rotation for departments that need reliable round-the-clock coverage.

The “24” means you report to the station in the morning (typically 7 or 8 AM) and stay for a full 24 hours, through the night, until the next team relieves you the following morning. During that time, you respond to calls, maintain equipment, train, eat, and sleep at the station (when calls allow it).

The “48” is your recovery time. Two full days off before your next shift. That’s enough time to handle personal business, spend time with family, and actually rest before doing it again.

How the 24/48 Schedule Rotation Works

The 24/48 schedule cycle is as simple as shift schedules get:

1. Day 1: Work a 24-hour shift (e.g., 8 AM to 8 AM)
2. Days 2-3: Off

Three teams (A, B, C) rotate through this pattern, staggered by one day. On any given day, one team is at the station, and two teams are home. The cycle repeats every 3 days, which means your work days follow a predictable pattern that’s easy to track.

Because the 3-day cycle doesn’t align with the 7-day week, your shift days rotate through the week. If you work Monday this week, you’ll work Thursday next week, then Sunday, then Wednesday, and so on. Over time, you work every day of the week equally. This is a common trait of rotating shift schedules, though patterns like the Pitman schedule handle the weekly alignment differently.

Day-by-Day Breakdown (All 3 Teams)

Here’s a 9-day view showing how the three teams rotate. W = Working (24 hours), – = Off.

Every day, exactly one team is on duty. The pattern is perfectly balanced: each team works the same number of shifts over any period.

24/48 Schedule Hours, Overtime, and Pay

On a 24/48 schedule, you work one 24-hour shift every 3 days. That works out to:

• ~10 shifts per month (varies by month length)
• ~122 shifts per year
• ~2,920 hours per year
• ~56 hours per week average

Fire departments operating a 24/48 schedule follow different overtime rules than most workplaces. Under the FLSA Section 7(k) exemption, fire departments can use work periods of 7 to 28 days with higher overtime thresholds. Many departments using the 24/48 schedule apply a 27-day work period with a 204-hour threshold (instead of the standard 40 hours/week).

Firefighter pay on a 24/48 schedule varies significantly by department, region, and rank. Many firefighters supplement their income with overtime shifts, side jobs during their 48 hours off, or paramedic certifications that come with pay bumps. For a different perspective on hours and pay, check how the Kelly schedule reduces average weekly hours to about 53.

The Real Pros and Cons of the 24/48 Schedule

What Makes It Worth It

• 2 full days off between every shift. That’s 48 hours to recover, handle life, and be present for your family. Most shift workers on 12-hour rotations don’t get this kind of consistent recovery time.
• Simple and predictable. Work every third day. That’s the whole pattern. You can plan months ahead without checking a calendar.
• Only 10 work days per month. You’re at the station about 10 days out of 30. The other 20 are yours. That ratio is hard to beat.
• Time for side work or education. Many firefighters use their 48 hours off for second jobs, paramedic school, college courses, or personal projects. The schedule practically encourages it.
• Strong team bonds. You spend 24 hours with your crew, eating together, training together, responding to calls together. The camaraderie in fire service is real, and the 24-hour shift format is a big part of why.

What’s Hard About It

• 24 hours is a long time to be on duty. Especially on busy nights. If you’re running calls from midnight to 4 AM, you’re not sleeping. And you still have to function until relief arrives at 8 AM. Research from the CDC’s NIOSH program confirms that sleep deprivation on extended shifts is the biggest health concern for workers on a 24/48 schedule.
• The 24/48 schedule means 56 hours per week. Compared to the 42-hour average of the 2-2-3 or DuPont, firefighters on a 24/48 schedule work significantly more hours. The trade-off is the concentrated schedule: fewer work days, but longer ones.
• Busy stations are brutal. In high-call-volume stations, you might get 2-3 hours of sleep during a 24-hour shift. Over time, chronic sleep deprivation takes a real toll on health and performance.
• Missing family events. You’ll work every third holiday, every third birthday, every third weekend day. The rotating nature means you can’t always be there for the moments that matter.
• Physical demands compound. Firefighting is physically demanding work. Doing it for 24 hours straight, especially after interrupted sleep, increases injury risk.

Who Uses the 24/48 Schedule?

• Fire departments. The 24/48 schedule is the most common fire service schedule in the U.S. From small volunteer departments to mid-size career departments, the 24/48 is the default. More on firefighter shift calendars.
• EMS agencies. Many ambulance services and paramedic units run 24/48 rotations, especially those co-located with fire stations.
• Rural emergency services. Smaller agencies that can’t staff enough people for shorter shifts often use 24-hour shifts out of necessity.
• Some police departments. A few law enforcement agencies use 24-hour shifts, though 12-hour patterns like the Pitman or 2-2-3 are more common for police. More on police shift schedules.

24/48 Schedule vs Kelly Schedule

The Kelly schedule is the 24/48 schedule’s more generous cousin. Both use 24-hour shifts with 3 teams, but the Kelly adds an extra day off every third cycle.

The Kelly schedule reduces your average weekly hours by about 3 hours and gives you a 4-day break every 9 days. Most firefighters prefer the Kelly over the 24/48 schedule if their department offers it. The 24/48 schedule is simpler but works you harder.

24/48 Schedule vs 48/96

The 48/96 schedule is gaining popularity in fire departments. Instead of working 24 hours and getting 48 off, you work 48 consecutive hours and get 96 hours (4 days) off.

The 48/96 cuts your commutes in half and gives you 4 consecutive days off, which many firefighters love for travel and family time. The downside is spending 48 straight hours at the station, which can be exhausting on busy shifts. Both the 24/48 schedule and 48/96 average the same weekly hours. If you’re looking for something in between, the Kelly schedule offers 4-day breaks without the 48-hour marathon.

Tips for Working 24/48 Schedule Shifts

Getting Through the 24 Hours

• Sleep when you can. This sounds obvious, but it’s the most important advice. When there’s a lull in calls, rest. Don’t stay up watching TV or scrolling your phone. Every hour of sleep you bank is an hour of better performance later.
• Eat real food. Station cooking is a tradition for a reason. A proper meal at dinner keeps your energy up through the night. Avoid heavy snacks at 2 AM since they’ll make you sluggish.
• Stay hydrated. Especially during calls. Dehydration compounds fatigue and slows your thinking. Keep water accessible.
• The 3-5 AM window is the hardest. Your body’s circadian low point. If you’re not on a call, try to rest. If you are on a call, be extra careful since this is when fatigue-related mistakes happen.

Making the Most of Your 48 Off

• Get a real sleep your first night home. Don’t try to power through the day. Get home, eat, sleep. You’ll feel human again by the next morning.
• Day 2 is your productive day. You’re rested and you have a full day before your next shift. Use it for errands, family time, exercise, or whatever matters to you.
• Sync your 24/48 schedule calendar. Use our free 24/48 calendar generator to create your shift calendar and share it with your family. When everyone can see your 24/48 schedule, planning gets much easier. You can also use our shift schedule maker to compare different patterns side by side.
