C Program to find day of week given date

I have a calendar file that gives dates as "20121027T190000" and I need to convert that to "Wednesday, October 27 2012, 1900". Is there a C function that computes the day of the week?

Yes, the standard localtime() function converts from a time_t to a struct tm that includes the day of the week. To create a time_t value, you can use the mktime() function to convert from a struct tm to a time_t (you do not have to fill in the day of the week when using mktime()).

This might seem like a roundabout way to do this, but it's reasonably straightforward and uses standard library functions.
