I keep my horses on my property and here is a general outline of the care I do daily.
7am I will go out and feed them their breakfast feed, either hay or hard feed. I will give them fresh water, take off their rugs if it is warm, or do a check under the rugs if it is cold(for injuries etc).
8am I take them down to their day paddock. Check they have enough water for the day and that there are no dangerous objects in the paddock. Check fences etc.
3pm I will get the horse I wish to ride that day ready, groom and saddle, take him into the arena and work him for a good 1/2 to an hour.
4pm cool horse down, either wash(warm weather) or brush him down, rug him up for the night and put him in their night paddock.
Retrieve the other horses and put them in their night paddock. Rug them up for the night.
5pm check water, pick up manure in both paddocks, check over all the horses, check paddocks.
6pm, feed them their nightly feed, usually a hard feed.
10pm last check, check horses are comfortable etc, and give them each a biscuit of hay.
There you go, that's a day in the life of a horse owner!!! Well at least one that has them on their own land!!
Hope it helps!
