In English, the days of the week have single-letter abbreviations (M, T, W, etc.) and three-letter abbreviations (Mon., Tue., Wed.). What are the standard ways to abbreviate the days of the week in Spanish?

I don't know if there's any official standard about this, but:

The single-letter abbreviations are:

L, M, X, J, V, S, D

Note that miércoles is usually written as X, so as not to confuse it with martes.

Regarding múltiple letter abbreviations, the usual way is two-letter abbreviations:

Lu, Ma, Mi, Ju, Vi, Sa, Do

I've seen the single-letter abbreviations, and the straightforward three-letter abbreviations, but never the two-letter ones you mention. – Peter Taylor Jan 17 '12 at 13:12
On the contrary, the two-letters forms is the most used in my experience (Argentina). – leonbloy Jan 18 '12 at 21:09
