2-2-3 Schedule: How It Works and When to Sleep

2-2-3 Schedule: How It Works and When to Sleep

A 2-2-3 schedule is a 14-day rotation of 12-hour shifts: work 2, off 2, work 3, then off 2, work 2, off 3. You work 7 shifts (84 hours) every two weeks, never more than 3 in a row, and get every other weekend off as a 3-day break. It is also called the Pitman schedule or Panama schedule.

Most pages about this rotation are written for the manager. This one is for you. Below: the 14-day table, a sleep plan for day and night blocks, caffeine cutoffs, and how to flip back on your days off.

Key Takeaways

• The 2-2-3 gives you 7 shifts per 14 days (84 hours, averaging 42/week), with a max run of 3 consecutive shifts.
• Sleep is the fix, not caffeine. A 12-hour shift plus commute leaves ~10 hours. Protect at least 7 for sleep (CDC).
• Front-load caffeine in the first half of every shift. Drake et al. 2013 (n=12) found 400 mg taken 6 hours before bed still cut total sleep by over an hour.
• The drive home after a night shift is the most dangerous part of the rotation.

How the 2-2-3 Work Schedule Works

Four crews share the 24-hour clock: two on days, two on nights, each following the same on/off pattern but offset. Here is one crew's 14-day cycle:

That is 7 twelve-hour shifts in 14 days: 84 hours total, averaging 42 hours per week. With a Sunday-to-Saturday pay week, the split lands at 36 hours one week and 48 the next. The exact split depends on where your employer's workweek begins.

Your "short week" has 2 work days. Your "long week" has 3 in a row but also gives you the 3-day weekend. Across a year: roughly 182 shifts.

Fixed 2-2-3 vs. Rotating 2-2-3 (Days and Nights)

Fixed: you stay on days or nights permanently. Your body clock adjusts once; the challenge is maintaining anchor sleep on days off.

Rotating: crews swap between days and nights every 2 to 4 weeks. This version is sometimes called the Panama shift pattern. The "flip" between day sleep and night sleep is the hardest part.

If you always clock in at the same time, yours is fixed. If you switch between days and nights, it is rotating. The sleep plans below cover both. If your site runs a DuPont rotation instead, see the DuPont schedule sleep and caffeine plan.

When to Sleep on a 2-2-3 Day Block

Example shift: 7:00 a.m. to 7:00 p.m. Adjust all times if your start is different. The principle is the same: protect 7 or more hours of sleep, and keep caffeine in the first half of the shift.

All clock times are examples. The non-negotiable part: no caffeine after the midpoint of the shift. A 7 a.m. start means last caffeine by noon, leaving roughly 9.5 hours of clearance before bed given caffeine's 5-to-6-hour half-life. On your first off day, sleep in. That is recovery, not laziness.

When to Sleep on a 2-2-3 Night Block

Example shift: 7:00 p.m. to 7:00 a.m. Night blocks are harder. You are sleeping against your circadian clock, and the first night is the worst.

The Pre-Night Nap

Before your first night shift, take a 1.5-to-3-hour nap in the afternoon. NIOSH cites studies showing this prophylactic nap improves alertness during the second half of the night. Nurses who napped 1.5 hours before their first night reported better alertness in the last half of the shift.

Day Sleep After Night Shifts

Get home, go straight to bed. Target roughly 8:30 a.m. to 3:30 p.m. (7 hours). Before you leave work, put on blue-light-blocking sunglasses (wraparound style is best) and keep them on until you are in a dark room (NIOSH). Dark curtains, cool room, phone on silent.

Caffeine at the start of the shift only. None in the last 6 hours before planned sleep. For a night worker sleeping at 8:30 a.m., that means no caffeine after roughly 2:30 a.m. For a full hour-by-hour plan, see the night shift caffeine schedule.

How to Flip Back on Your Days Off

After your last night shift, you need to get back on a daytime schedule:

1. Short morning sleep. Sleep about 4 hours (8:00 a.m. to noon). Set an alarm.
2. Get outside. Afternoon daylight helps reset your body clock.
3. Normal bedtime that night. You will be tired. Bed at 10:00 to 11:00 p.m., sleep through.

If you only have a 2-day break inside a night block, flipping twice in one week is brutal. One option: stay partly on a night schedule (sleep roughly 3:00 a.m. to 11:00 a.m.) so you skip the double adjustment. Neither approach has been tested in a controlled trial for the 2-2-3. Pick whichever protects the most total sleep. Can the 3-day weekend repay lost sleep? Partially.

Caffeine on a 2-2-3: A Bridge, Not the Fix

Caffeine helps you stay alert. It does not replace sleep. NIOSH is direct: stimulants do not provide the alertness and decision-making ability that comes from adequate sleep.

The pharmacology matters. Caffeine takes about 30 minutes to take effect, has a half-life of 5 to 6 hours, and can linger much longer in some people. The FDA cites 400 mg per day as the amount not generally associated with negative effects for most healthy adults.

Rules of thumb:

• Front-load it. Caffeine at the start of the shift, not the middle.
• Smaller doses beat one large one. Two 80-to-100 mg doses spaced 3 to 4 hours apart sustain alertness without a spike-and-crash.
• Hard stop 6+ hours before planned sleep. Day worker in bed by 9:30 p.m.: no caffeine after 3:30 p.m. Night worker sleeping at 8:30 a.m.: none after 2:30 a.m.
• Caffeine nap on break. Caffeine right before a short nap (20 to 30 min). It kicks in as you wake (NIOSH). See how to time a caffeine nap.
• Daily heavy use blunts the effect. NIOSH notes that heavy daily caffeine may no longer increase alertness.

For getting through the 3 to 4 a.m. low point, see staying alert through the 4 a.m. dip and what to take to stay awake on nights.

The Drive Home Is the Most Dangerous Part of the Rotation

NIOSH data shows that being awake for 17 hours produces impairment similar to a 0.05% BAC. At 24 hours awake, it is equivalent to 0.10%, above the US legal limit.

Drowsy-driving crashes peak between 4:00 and 6:00 a.m., exactly when night-shift workers head home. People sleeping 6 to 7 hours a night are twice as likely to be in a sleep-related crash as those sleeping 8 or more; under 5 hours raises risk 4 to 5 times (AAA Foundation for Traffic Safety, 2016). 1 in 10 nurses reported a crash they believed was related to shift-work fatigue.

The fixes: do not drive drowsy. Nap before leaving. Get a ride. Pull over and sleep. Caffeine plus a short nap before the drive is a bridge (NIOSH), never a license to drive tired. See the drowsy driving warning signs checklist.

Pay and Overtime on a 2-2-3

Under the federal FLSA, covered nonexempt employees earn time-and-a-half for hours over 40 in a workweek. On a 36/48 split, the 48-hour week carries 8 overtime hours. The FLSA does not cap weekly hours for workers aged 16 and older. State law, union contracts, and exemptions vary. Check your pay stub. This is not legal advice.

The Pattern Is Manageable if You Protect the Sleep

The 2-2-3 is built for coverage, not for your circadian system. But you never work more than 3 in a row, and a 3-day break comes every other week. The workers who do well on this rotation treat sleep as infrastructure, not as whatever time is left. Front-load caffeine. Black out the bedroom. Nap before the first night. Plan the drive home. The schedule is fixed. Your sleep plan should be too.

Frequently Asked Questions

How many hours a week is a 2-2-3 schedule?

42 hours per week on average (84 hours per 14 days). The actual weekly split depends on your employer's workweek. A common breakdown is 36 and 48, with 8 overtime hours in the longer week under the federal FLSA.

Is the 2-2-3 the same as the Pitman or Panama schedule?

Yes. The Pitman schedule and Panama schedule describe the same 2-on, 2-off, 3-on/off pattern of 12-hour shifts across a 14-day cycle. Different industries use different names, but the rotation is identical.

How many days off do you get on a 2-2-3?

You get 7 days off every 14 days: a 3-day weekend every other cycle and two 2-day breaks. Across a year, roughly 182 shifts and 183 days off.

How do you sleep when a 2-2-3 rotates between days and nights?

Day blocks: bed by 9:30 to 10:00 p.m., wake around 5:30 a.m. Night blocks: sleep as soon as you get home (roughly 8:30 a.m. to 3:30 p.m.) in a dark, cool room, with a 1.5-to-3-hour nap before the first night. To flip back: sleep 4 hours after the last night, get afternoon daylight, bed at a normal hour.

Is a 2-2-3 schedule bad for your health?

Shift work and chronic short sleep carry known health risks. The 2-2-3 limits consecutive shifts to 3, which is better than some rotations, but 12-hour shifts still compress recovery. If you experience persistent insomnia or excessive daytime sleepiness, see a clinician. No 12-hour night rotation is easy on the body.

When should I stop caffeine on a night shift?

At least 6 hours before planned sleep. On a 7 p.m. to 7 a.m. shift with sleep at 8:30 a.m., that means no later than 2:30 a.m. The Drake et al. 2013 study showed 400 mg taken 6 hours before bed still cut sleep by over an hour. Smaller doses clear faster, but earlier is always better.

One Dose at the Start of the Shift, Then Nothing Before Bed

The rule this article keeps returning to: caffeine early, nothing late. A 12-hour shift does not need a refill cycle. It needs one dose that carries, taken at clock-in, with a hard stop well before sleep.

That is the problem Roon was built around. Each pouch delivers 80 mg caffeine, 60 mg L-theanine, 25 mg methylliberine (Dynamine), and 5 mg theacrine (TeaCrine) as a zero-nicotine, zero-sugar sublingual pouch (the formula contains sucralose). Felt window: 6 to 8 hours, designed as a single dose rather than stacked refills.

The duration comes from methylliberine slowing caffeine clearance. A randomized, double-blind crossover PK study (n=12) found that 100 mg methylliberine co-administered with 150 mg caffeine cut caffeine's oral clearance from 41.9 to 17.1 L/hr and extended its half-life from 7.2 to 15 hours, with no increase in peak concentration. That study used 4x the methylliberine and ~1.9x the caffeine in a Roon pouch (25 mg + 80 mg), so the numbers are directional, not a direct measurement of the product.

The trade-off matters for shift workers: a longer tail means you stop earlier. Roon's guidance is at least 8 hours before bed. For a night worker sleeping at 8:30 a.m., that means one pouch at 7 p.m. and nothing after midnight. Roon is not a substitute for sleep, not a reason to skip the pre-shift nap, and not a license to drive drowsy. From $9.16 per tin on a 12-tin subscription ($0.61 per pouch), or $15.00 per tin one-time. Try Roon.
