N.J. Stat. § 34:15-38
To calculate the number of weeks and fraction thereof that compensation is payable for temporary disability, determine the number of calendar days of disability from and including as a full day the day that the employee is first unable to continue at work by reason of the accident, including also Saturdays, Sundays and holidays, up to the first working day that the employee is able to resume work and continue permanently thereat; subtract from this number the waiting period and any days and fraction thereof the employee was able to work during this time, and divide the remainder by 7. If, however, the total period of disability extends beyond 7 days, the waiting period shall not be subtracted from the number indicated above. The resulting whole number and sevenths will be the required period for which compensation is payable on account of temporary disability.
