What is the reduced night hour?

In urban work a night hour is 52 minutes 30 seconds: 7 clock hours count as 8.

Is this an official figure?

It applies the CLT rules and the 2026 tables; a collective agreement or the payroll may differ.

Do I enter clock hours or night hours?

Clock hours, as worked: 20 nights from 23h to 5h are 120 hours. The page turns them into night hours itself — × 60 ÷ 52,5 gives 137,14 h for urban work. Rural work has no shorter hour, so 120 clock hours stay 120.

Which month should I choose?

The month the nights were worked. The DSR is the premium ÷ that month’s working days (Monday to Saturday) × its Sundays and national holidays: March 2026 has 26 and 5, April 2026 has 24 and 6. State and town holidays are not counted.

Example

Example: a hotel night receptionist, 23h to 5h, 20 nights in March 2026

A night receptionist at a hotel in São Paulo earns R$ 2,400.00 a month on a 36-hour week and works six-hour nights from 23h to 5h. In March 2026 she worked 20 nights. Settings: Monthly hours 180; Work: Urban; Schedule: Enter the hours; Month: any day in March 2026.

Clock hours in the night window: 120 (20 × 6), all between 22h and 5h. Hours after 5h stay empty, as her shift ends at 5h.
An urban night hour is 52 minutes 30 seconds, so the page counts 137,14 h = 120 × 60 ÷ 52,5.
Hourly value: R$ 13,33 = R$ 2.400,00 ÷ 180. Premium at 20 %: R$ 365,71 = 137,14 h × R$ 13,33 × 0,2.
Reflex on the DSR: R$ 70,33 = R$ 365,71 ÷ 26 × 5, since March 2026 has 26 working days (Monday to Saturday) and 5 Sundays, with no national holiday.

Same 120 clock hours	Hourly value	Premium	DSR	Total
March 2026, 180 hours	R$ 13,33	R$ 365,71	R$ 70,33	R$ 436,04
April 2026, 180 hours (24 working days, 6 rest days)	R$ 13,33	R$ 365,71	R$ 91,43	R$ 457,14
March 2026 on a 220-hour contract	R$ 10,91	R$ 299,22	R$ 57,54	R$ 356,76
March 2026, rural livestock work, 20h–4h, 25 %	R$ 13,33	R$ 400,00	R$ 76,92	R$ 476,92

The page shows Night premium with the DSR: R$ 436,04 for March. The same nights in April give the same premium, but Good Friday and Tiradentes add two rest days, so the DSR rises to R$ 91,43 and the total to R$ 457,14.
