Example: 15 nights on a 12x36 rota in December 2026, on a R$ 3,150 salary
A nursing technician at a hospital in Brazil works nights from 19h to 7h on a 12x36 rota, earning R$ 3,150.00 a month on a 220-hour contract (urban work). In December 2026 she worked 15 nights. The salary can be typed 3,150.00 or 3.150,00; the page shows amounts the Brazilian way, as on a payslip.
- Each night has 7 hours between 22h and 5h and 2 hours after 5h that continue it: 15 × 9 = 135 clock hours.
- An urban night hour is 52 minutes 30 seconds, so the page counts 154,29 h = 135 × 60 ÷ 52,5.
- Hourly value: R$ 14,32 = R$ 3.150,00 ÷ 220. Premium at 20 %: R$ 441,82 = 154,29 h × R$ 14,32 × 0,2.
- Reflex on the DSR: R$ 84,97 = R$ 441,82 ÷ 26 × 5, since December 2026 has 26 working days (Monday to Saturday) and 5 Sundays and holidays, Christmas falling on a Friday.
| 15 nights in | Working days / Sundays and holidays | Premium at 20 % | DSR | Total |
|---|---|---|---|---|
| November 2026 | 23 / 7 | R$ 441,82 | R$ 134,47 | R$ 576,29 |
| December 2026 | 26 / 5 | R$ 441,82 | R$ 84,97 | R$ 526,79 |
| January 2027 | 25 / 6 | R$ 441,82 | R$ 106,04 | R$ 547,86 |
For 15 nights in December 2026 the page shows Night premium with the DSR: R$ 526,79. The premium itself is the same every month for the same nights; only the DSR changes with the month’s Sundays and holidays. With 16 nights in December the total is R$ 561,90; with 14, R$ 491,66.

Frequently asked questions
- How many night hours in a 12x36 night?
- From 19h to 7h: 7 between 22h and 5h and 2 after 5h, all with the premium.
- Is this an official figure?
- It applies the CLT rules and the 2026 tables; a collective agreement or the payroll may differ.
- How is the night premium worked out on a 12x36 rota?
- Nights × 9 clock hours (7 between 22h and 5h, 2 after 5h), × 60 ÷ 52,5 for the shorter night hour, × the hourly value (salary ÷ monthly hours) × 20 %, then the DSR reflex is added. With R$ 3.150,00 on 220 hours and 15 nights, that is R$ 441,82 of premium and R$ 526,79 with the DSR for December 2026. Amounts are shown the Brazilian way, with a decimal comma.
- Why does the same number of nights pay a different amount each month?
- Because of the DSR, the paid weekly rest: the premium is divided by the month’s working days (Monday to Saturday) and multiplied by its Sundays and national holidays. December 2026 has 26 and 5, November 2026 has 23 and 7, so 15 nights give R$ 526,79 in December and R$ 576,29 in November. Pick the month the nights were worked.
