Day-of-Week with Dates
When a weekday accompanies a date, capitalize the weekday and follow the date order and punctuation of the chosen style. Microsoft prefers spelling weekday names out in running text and reserves abbreviations for space-constrained contexts.
Capitalize weekday names; spell them out in ordinary prose unless space is tight, then apply the date punctuation required by your chosen style.

Weekday names are proper-name-like calendar labels and are capitalized; Microsoft advises against abbreviating them unless space is limited.
