If you’re giving someone instructions—like how often to take a medication—or simply talking about a routine, the phrase “every other day” comes up a lot. But how do you say that in Spanish?
Let’s look at four common ways to express this idea and how native Spanish speakers use them in real life.
1. Un día sí, un día no
Literal translation: One day yes, one day no
This is probably the most natural and commonly used way to say “every other day” in conversation or medical settings.
🗣 Examples:
- Tómese esta pastilla un día sí, un día no.
(Take this pill every other day.) - Hago ejercicio un día sí, un día no para descansar.
(I work out every other day to rest in between.)
This structure is super easy to use and sounds very natural in many Spanish-speaking countries.
2. Un día por medio
Literal translation: One day in between
This phrase is slightly more formal and may be used in written instructions or in some regions.
🗣 Examples:
- El medicamento se administra un día por medio.
(The medication is given every other day.) - Me lavo el cabello un día por medio.
(I wash my hair every other day.)
3. Días alternos
Literal translation: Alternate days
This is more technical or clinical and often used in written medical instructions, research, or formal communication.
🗣 Examples:
- Aplicar la crema en días alternos.
(Apply the cream on alternate days.) - Se realizarán controles médicos en días alternos.
(Medical check-ups will be done on alternate days.)
4. Cada dos días
Literal translation: Every two days
While not an exact match for “every other day,” this phrase is often used as a simplified version and works in most contexts.
🗣 Examples:
- Cambie el vendaje cada dos días.
(Change the bandage every two days.) - Tomo clases de español cada dos días.
(I take Spanish classes every two days.)
Just note: this can sometimes include a two-day break, depending on interpretation—so it’s not always identical to “every other day.”
