Sadly, I'm more productive around after midnight.

I'm usually most productive from 2am to whenever I fall asleep, which has been somewhere between 10am and noon as of late. Great sleeping cycle, I know :) It's almost impossible to get anything done during the day, especially on a college campus - so many distractions!

For me the hour depends on how excited I am about the project i'm working on, could be night, morning, doesn't matter. However my best ideas happen at night.

My so-called "day work" is usually from 10am-10pm and I tend to be more productive from 6 -8(pro-dinner). Side-project-wise maybe 12-2am.

I find myself focus better after 11pm to whenever i sleep. Probably because there's less distractions around this time of the day.

Wow, same as everyone, I'm most productive at night until morning.

I tend to be most productive around 11pm, till I fall asleep.

It's very pity, but I am the most productive at night.

Right before a deadline.

early morning. i get maximum work done between 6am-10am.

strange you ask, but i guess just like most will admit here, productivity is at peak for me in the cold hours of the night. It's like darkness brings with it some aura of heightened awareness and gravitation to creative work - code at least.
