In this article, we will explore the differences between Buenos Dias and Buenas Dias and provide you with some tips on when to use each one. So, let’s get started.

Buenos Dias vs. Buenas Dias

The phrase Buenos Dias translates to “good morning” in English. The word Buenos is an adjective that agrees in gender and number with the noun it modifies, which in this case is Dias (days), a masculine plural noun. Therefore, the correct translation of Buenos Dias is “good mornings.”

On the other hand, the phrase Buenas Dias may sound correct, but it is actually grammatically incorrect in Spanish. The word Buenas is a feminine plural adjective that agrees in gender and number with a feminine plural noun. Since Dias is a masculine plural noun, the correct feminine plural adjective to use should be Buenas instead of Buenos. Therefore, the correct way to say “good days” in Spanish is Buenas Dias.

When to Use Buenos Dias

Buenos Dias is commonly used as a morning greeting. It is also used as a way to say “have a good day” or “goodbye” to someone in the morning. This phrase is appropriate to use in any situation where you want to greet someone in a polite and respectful manner in a morning setting.

For example, if you are passing by someone on the street in the morning, you can greet them by saying “Buenos Dias” with a smile. Similarly, when you enter a shop or a restaurant in the morning, it is polite to greet the staff by saying “Buenos Dias” to acknowledge their presence.

When to Use Buenas Dias

As we mentioned earlier, Buenas Dias is not a correct Spanish phrase, and using it can be seen as a mistake. However, if you want to use the phrase “good days” in a conversation, you can say “Deseo que tengas buenos días” or “Que tengas un buen día” instead.

It is important to use the correct gender and number of the adjective when using Spanish greetings. Using the wrong form of the adjective can make your message confusing or show a lack of understanding of the language.


In conclusion, Buenos Dias is the correct and common way to say “good morning” in Spanish. On the other hand, Buenas Dias is grammatically incorrect and should be avoided in Spanish conversations.
