Quick answer
Dia is the day itself; data identifies its place on the calendar.
A reliable test is to identify the job of the word before translating from English.
What each word does
dia
day
Use dia for a day as a period of time or an experience.
data
calendar date
Use data for the numbered day, month, and often year assigned to an event.
How to choose
- dia: Choose dia if the sentence points to a day as a period of time or an experience.
- data: Choose data if the sentence points to the numbered day, month, and often year assigned to an event.
Examples
Hoje foi um dia longo.
Today was a long day.
Qual é a data da reunião?
What is the date of the meeting?
Common trap
Data is not the ordinary word for a romantic date. Depending on the situation, use encontro or sair com alguém.
Practice it in context
Pick one sentence from your real life and write it twice: once with dia, then once with data. If both versions feel possible, name the meaning shift.
