I have the same routine 7 days/week.
7:00 am - feed horses in stalls, take hay and water out to the paddocks while they are eating, turn out the horses, giving each horse a quick check over and brush off and blanketing as needed, clean stalls, put hay in stalls, clean out and refill water buckets and sweep and tidy up barn
Noontime - noontime check, feed, hay, check water
5:00 pm - bring horses in from turnout, quick check over and change blankets as needed, feed (in winter this happens earlier around 4:00, sometimes when it is nicer out, like right now in the springtime, it is later around 6:00)
9:00 pm - night check, feed, hay, water, quickly muck out stalls
If the weather is really bad I may keep them in and then if it is better by noontime they go out then, if not they just stay in for the day. Or, if the weather turns bad by noontime I will bring them in then. On these days the stalls are mucked out at each one of the times above.
I fit in riding/exercise times in between the times listed above, weather permitting. I spend time grooming every day even if I don't get the chance to ride if the weather is bad.
Also, it might look like they get a lot of feed, since I give them 4/day, but I only give them small amounts at a time of high fat/high fibre feed and a ration balancer.
