How to say weekdays with “Na” and “No” in Portuguese basics

Introduction

This article explains how to say weekdays with na and no in Brazilian Portuguese. You will learn the grammar rule, see clear examples, learn common phrases, and practice with everyday sentences. The focus is practical: making schedules, answering questions, and writing messages correctly as a beginner.

Why na and no matter for weekdays

In Brazilian Portuguese, prepositions combine with definite articles to form contractions. Two very common contractions for talking about days are na and no. They are required when you say on a day paired with a location or a part of the day, or when the noun needs a definite article. Learning these helps your phrases sound natural and grammatically correct.

Basic rule: when to use na and no

no is the contraction of em + o. Use no before masculine singular nouns. Example:

no sábado

na is the contraction of em + a. Use na before feminine singular nouns. Example:

na terça-feira

Weekday names in Brazilian Portuguese can be used with or without articles. Some weekdays are treated as masculine and others as feminine when combined with the definite article. For beginners it is simplest to memorize which weekdays commonly appear with no or na.

Weekday vocabulary and gender

Here are the common weekday names and the usual article gender you will encounter in Brazilian Portuguese.

segunda-feira — feminine (use na)

terça-feira — feminine (use na)

quarta-feira — feminine (use na)

quinta-feira — feminine (use na)

sexta-feira — feminine (use na)

sábado — masculine (use no)

domingo — masculine (use no)

Notes about names and usage

Weekdays from segunda-feira to sexta-feira include the feminine word feira, which makes them naturally feminine in many contexts. Saturdays and Sundays are standalone masculine nouns. However, in casual speech Brazilians sometimes drop feira: e.g., terça. Even then, many speakers keep the feminine agreement. For beginners, treating segunda through sexta as feminine and sábado/domingo as masculine is reliable.

How to form sentences with na and no

Use no or na before the weekday when the verb or preposition requires em or when you want to express on a specific day. Common sentence patterns:

Tenho aula na segunda-feira.

O mercado abre no sábado.

Combine these patterns with times and places for natural sentences.

Examples with times and places

Practical daily phrases a beginner might use or see:

Tenho aula na segunda-feira às 9h.

Consultório fecha no sábado.

Short dialogues and messages

Here are short realistic examples of messages and conversations using na and no. These are the type of sentences you might write in a text or hear in a simple conversation.

Example 1 — arranging a meeting:
Vamos nos ver na terça-feira às 18h?

Response:
Sim, posso. Te encontro no shopping perto da estação.

Example 2 — changing plans:
O restaurante abre na quinta-feira à noite, certo?

Reply:
Não, abre só no fim de semana.

Example 3 — schedule notice on a door:
Fechado na segunda-feira.

Example 4 — short social media note:
Aula cancelada no sábado. Próxima aula na segunda-feira.

Common beginner mistakes and how to avoid them

Mistake 1: Using em + weekday without contraction
Incorrect: em o sábado — sounds wrong and unnatural. Correct: no sábado.

Mistake 2: Treating all weekdays as feminine or masculine
Incorrect: em a domingo. Correct: no domingo.

Mistake 3: Omitting article when the context needs it
Sometimes Portuguese uses the article naturally: dizer na quinta-feira is more natural than dizer quinta-feira in specific scheduling contexts. If you want to be safe, use na for segunda–sexta and no for sábado/domingo when saying on a day.

Quick tip for tests and practice
