Sorry Posted in wrong forum

I want to find the day of the week on which the 1st Jan falls in the year I input. For example: in A1 all I want to enter is a year e.g. 2006. In B1 I want a formula that will return the value SUNDAY. I can get the formula to work if I enter 1/1/06 in A1 but I just want to enter the year. I tried using Concatenate to add 1/1/ to the value in A1 but couldn't get excel to recognise the concatenation as a date. Any ideas?

thanks
