In Mexican Spanish,

  • "Ocho días" = One week
  • "Quince días" = Two weeks
  • "Una quincena" = Two weeks (one fortnight)
  • "Quincenal" = Every two weeks

Is this usage unique to Mexico?

(Some of the comments at this question made me wonder about this.)

It appears ocho días = one week is common in some regions. I've never heard it in Argentina, nor the expressions mentioned in the other question (such as de aquí en ocho). It's either siete días or una semana.

The equivalence of 15 days to two weeks, on the other hand, is common here, and I gather it's common elsewhere. Quincena is mostly used in reference to wages (for someone who gets paid every two weeks); metonymically, it refers both to the span of time and to the money itself.

If you go to a doctor and s/he wants a follow-up in two weeks, s/he will say either «Te veo en dos semanas» or «Te veo en quince días». This is so common that I guess nobody would mistake quince días for fifteen actual days unless in very specific contexts.

Quincenal is also usually "once a fortnight", but it may imply "twice a month".


Also commonly used in the Quito region of Ecuador; not sure if it's common on the coast.

I don't aknowledge that "ocho días" means "one week" in Spain. It seems to me that that exact wording is local Mexican usage.


As Mexican I can answer the same way the given answer in the post

A week is not made from 8 days, but when something is bound to happen into a week from the current day, we will say "8 days from/starting today"

Some explanation

  • 1 day is today (Monday)
  • 2 days will be tomorrow Tuesday
  • 3 days will be Wednesday
  • 4 days will be Thursday
  • 5 days will be Friday
  • 6 days will be Saturday
  • 7 days will be Sunday
  • 8 days will be Monday(again)

This means that "de hoy en 8" : "8 days from today" means that something is happening one week ahead.

Basically you count the days and add 1 (to include the current day in the counting)

  • Mike, now that you've gotten the hang of checking your spelling, how about fixing this post up? With special focus on "weak"? In terms of content, I do like this post. I'd like to be able to change my vote. Commented Jan 23, 2020 at 8:12
