✦Grammar Breakdown
Nossoaniversárioédia21deabril
Nosso
This is a possessive adjective meaning 'our'. It must agree in gender and number with the noun it modifies. 'Aniversário' is masculine singular, so 'nosso' is used.
aniversário
This noun can mean 'birthday' or 'anniversary'. The context, especially with 'nosso' (our), usually clarifies that it refers to an anniversary for a couple or group.
é (Ser)
This is the third-person singular form of the verb 'ser' (to be). 'Ser' is used for permanent characteristics, definitions, and to state dates and times, unlike 'estar' which is for temporary states.
dia
Meaning 'day'. When stating a specific date, 'dia' is commonly used directly before the number, often without an article, making the expression sound natural and complete.
de
This preposition means 'of' or 'from'. Here, it connects the day to the month, forming the standard way to express dates in Portuguese.
abril
This is the noun for the month 'April'. In Portuguese, months are typically not capitalized unless they begin a sentence.

✕Common Mistakes
Nosso aniversário é em 21 de abril.
While 'em' is used for months or years, for specific days, 'dia' is the more natural and common choice in Portuguese.
Nosso aniversário está dia 21 de abril.
The verb 'ser' (é) is used for dates and permanent facts, not 'estar' (está), which is for temporary states or locations.
Nosso aniversário é 21 de abril.
Although understandable, omitting 'dia' before the number makes the phrase sound less natural. Including 'dia' is standard when stating a specific day of the month.

Cultural Tip
