Wikipedia:Articles for deletion/Determination of the day of the week
While Wikipedia is not an instruction manual, descriptions of algorithms are perfectly acceptable; this is an article on day of week algorithms. Day of the week is a notable concept and so are algorithms for calculating the day of the week; such algorithms are needed for most calendrical calculations, manual or computational. Because the topic is notable and AfD is not for article cleanup (see  for details), this article should be kept. That said, the article does have weak points; the lead and Determination of the day of the week#Useful concepts|Useful concepts section are essay-like and need cleanup. But the subsequent sections, with concise descriptions of various algorithms, along with some references, seem fine
