Do You Count the Day of Injury on the OSHA 300 Log?
No. Do not count the day of the injury or the day the illness began; start counting days away or restricted days on the next calendar day.
The short answer
No. Do not count the day of the injury or the day the illness began; start counting days away or restricted days on the next calendar day. A restriction that applies only to the day of injury does not make the case recordable as restricted work.
The incident day is often mistakenly included in days away or restricted counts.
The rule in plain English
DART cases are the ones checked in column H (days away from work) or column I (job transfer or restriction) of the 300 Log. Each case is checked once, in the most serious column that applies (death, then days away, then restriction or transfer, then other), but both day counts are entered: days away in column K and restricted or transferred days in column L. Count calendar days, starting the day after the injury or illness began (29 CFR 1904.7(b)(3)). Restricted work means the employee cannot perform one or more routine functions (activities done at least once a week) or cannot work the full workday, whether you impose it or a provider recommends it (1904.7(b)(4)). You may stop counting at 180 days.
OSHA day-counting rules
From 29 CFR 1904.7(b)(3) and (b)(4):
- Start counting the day after the injury or illness began.
- Count calendar days, including weekends, holidays, and other days off the employee could not have worked because of the injury.
- If a provider recommends days away and the employee works anyway, record the recommended days.
- If a provider clears the employee to return and they stay home, stop counting on the date of the clearance.
- An injury on a Friday before a weekend off is a days-away case only if a provider says the employee should not have worked those days.
- A partial shift counts as a restricted day, except on the day of injury.
- You may stop counting at 180 days; entering 180 is enough.
- If the employee leaves for reasons unrelated to the injury, you may stop counting; if they leave because of it, estimate the total.
- A case that runs into the next year stays on the log of the year it occurred, with an estimate updated later.
How it plays out on site
Do not count the day of injury or illness onset when counting days away or restricted work. DART is where cases and days get confused: the rate counts cases, while the log also carries day totals that leadership often reads as the same thing. The fix is to track each case's status day by day (away, restricted, transferred, or full duty) and derive both the column and the day counts from that record.
As the safety manager you usually own the decision itself, so the most useful habit is writing down the fact each call rests on at the time you make it.
The common mistake
Teams count from the clinic visit time instead of the next calendar day.
Column H and I cases drive the DART rate and the 300A totals; the day counts in K and L go on the 300A too, and into the ITA file for covered establishments.
Edge cases
- Late-shift incidents can make the first counted day feel counterintuitive.
- A restriction that applies only to the day of injury does not make the case recordable as restricted work.
Worked example
An employee is injured at 11 p.m. on a Tuesday night shift, goes home, and returns to full duty on Friday. Wednesday and Thursday are days away; Tuesday is not counted, even though most of the shift was lost. The case shows 2 days in column K.
Checklist
- Record the incident date.
- Set the first counted day.
- Record the return date.
- Total the days.
What to keep in the case file:
- Provider notes with restriction dates and what was restricted
- The employee's routine functions, from a job analysis or supervisor
- Day-by-day status: away, restricted, transferred, or full duty
- Estimates for cases still open at year end and when they were updated
Where 300log helps
300log keeps days away and restricted days on each case, carries them into the 300A totals, and lets you update the counts as a case develops, so the posted summary and the DART rate come from the same entries.

Frequently asked questions
Do You Count the Day of Injury on the OSHA 300 Log?
No. Do not count the day of the injury or the day the illness began; start counting days away or restricted days on the next calendar day. A restriction that applies only to the day of injury does not make the case recordable as restricted work.
What is the maximum number of days to record?
You may cap days away, restricted work, or job transfer at 180 calendar days.
Is light duty always restricted work?
Only if the employee cannot perform one or more routine functions or cannot work a full shift. A light-duty label does not decide it by itself.
Do you count the day of the injury?
No. Start counting days away or restricted days on the day after the injury or illness began.
