Is it better to Code during the day or at night? (quora.com)

It's better to code when you are ready to code. For me that is from about 8AM to 12AM. After that my brain goes a bit mush - so I instead turn to administrative stuff. For you it could be totally different. This is why I don't chain my coders to their desks. They code when they code (baring ZOMGWTF all-hands-on-deck situations (which we actually haven't encountered yet)) and they produce better code for it.

As long as tasks get checked off I don't care when it happens.
