we don't have an export, but if you check ouy your activity tab: http://www.dotabuff.com/players/27958433/activity (and make sure it's set to your timezone). You can get a good sense of how much you played during those days. Although, it doesn't include filtering by work hours.

I'm currently writing down the extra days i had to work, so I was wondering if there was an easy way to check what days i didn't play during "worktime" ;D (the last 6 months)
If theres some way to export it, with dates, it would be really helpful.
