Opinion
Perry Eugene King appeals from the judgment entered on a jury verdict convicting him of discharging a firearm at an occupied building (Pen. Code, 1 § 246). In the published portion of the opinion we reject his contention that he is entitled to two additional days of conduct credit under section 4019 and the principle of equal protection of the laws.

Defendant received 47 days of actual custody credit and 22 days of good-time/work-time credit for a total of 69 days. He contends he is entitled to two additional days of conduct credit. Citing

v.
Perez
(1989)
The conduct credit statute, section 4019, subdivisions (b) and (c), state for each six-day period in which a prisoner is confined, one day shall be deducted from his period of confinement for satisfactorily performing labor, and one day shall be deducted for compliance with the rules and regulations of the facility. “If all days are earned under this section, a term of six days will be deemed to have been served for every four days spent in actual custody.” (§ 4019, subd. (f).)
Since the early 1980’s many courts approximated the conduct credit by multiplying the actual custody days by 1.5. (See, e.g.,

Defendant argues that the statutory interpretation and method of calculation adopted in

violates equal protection guarantees because it fails to give conduct credits for days of actual custody in excess of increments of four. Defendant relies on

v.
Sage
(1980)
In 1982, the Legislature codified Sage by amending section 4019 to provide for conduct credit in the case of pretrial felony detainees. Defendant contends the Legislature introduced a new equal protection violation by awarding conduct credit only after each block of four days is served. He contends there is no rational basis for giving the same amount of conduct credit to detainees who have behaved appropriately for a period of time divisible.by four as is awarded to detainees who have served four-day increments as well as additional days not divisible by four.
The concept of the equal protection of the laws compels that persons similarly situated with respect to the legitimate purpose of the law receive

v.
Rosala
(1984)
Assuming the equal protection clause applies to pretrial detainees held for multiples of four days and those held for periods that are not even multiples of four, we conclude there is a rational basis for the four-day increment method of calculation. Section 4019 awards two distinct kinds of credit. Section 4019, subdivision (b) authorizes one day of credit for each four-day period of confinement if the prisoner has performed assigned labor. Section 4019, subdivision (c) authorizes one day of credit for each four-day period of confinement if the prisoner has satisfactorily complied with the rules and regulations of the institution. The Legislature apparently determined the appropriate ratio for awarding each type of compliant behavior is a reduction of sentence by one day for four days of appropriate behavior. The Legislature can rationally reward each type of behavior separately and in whole day increments as a reasonable accommodation to administrative practicality.
Defendant also contends there is a factual contradiction in awarding actual custody credits for days of partial custody but awarding conduct credit for only completed four-day custody periods. Not so; the difference is due to the language utilized in each statute.
Actual custody credits are awarded under section 2900.5 which provides “when a defendant has been in custody, ... all days of custody of the defendant . . . shall be credited upon his term of imprisonment.” Since section 2900.5 speaks in terms of “days” rather than “hours,” it is presumed the Legislature intended to treat any partial day as a whole day.

v.
Smith, supra,
On the other hand, the legislative intent expressed in section 4019 that “a term of six days will be deemed to have been served for every four days

spent in actual custody” is not ambiguous. When a statute is unambiguous, “ ‘there is no need for construction, and courts should not indulge in it.’ ”
