Months are lowercase
As with days of the week, Spanish writes the months with a small letter: Mi cumpleaños es en julio (My birthday is in July). Capitalize one only at the start of a sentence or in a title.
Septiembre has a second accepted spelling, setiembre, used in some countries such as Peru and Uruguay. Both are correct.
How to say and write dates
Spanish dates go day, month, year, joined with de, and use ordinary numbers rather than "first, second, third":
| Spanish | English |
|---|---|
| el 5 de mayo | May 5 (May fifth) |
| el 16 de septiembre de 2010 | September 16, 2010 |
| el primero de enero / el 1 de enero | January 1 |
| 5/3/2026 | March 5, 2026 (day first) |
The first of the month is often el primero, especially in Latin America; after that it is always the plain number: el dos, el tres. In short dates the day comes first, so 5/3 is March 5, not May 3.
- ¿Qué fecha es hoy? What’s the date today?
- Hoy es 14 de febrero. Today is February 14.
- ¿Cuándo es tu cumpleaños? When is your birthday?
- Es el 20 de agosto. It’s August 20.
In January, next month, every month
| Spanish | English |
|---|---|
| en enero | in January |
| a principios de marzo | at the beginning of March |
| a mediados de junio | in mid-June |
| a finales de octubre | at the end of October |
| el mes que viene / el próximo mes | next month |
| el mes pasado | last month |
| todos los meses | every month |
Seasons
The seasons are la primavera (spring), el verano (summer), el otoño (fall), and el invierno (winter). South of the equator, in Argentina, Chile, or Uruguay, the seasons are reversed: December is summer, and Navidad en verano (Christmas in summer) is normal.
Common mistakes
- Capital letters: write abril, not Abril.
- Ordinals for dates: say el 3 de mayo, not el tercero de mayo.
- Month first: 4/7 means July 4 in Spanish, not April 7.
- Forgetting de: say el 10 de junio, not el 10 junio.
- Pronouncing j: junio and julio start with a strong h sound: HOO-nyo, HOO-lyo.
