I fondly remember spending a summer playing this game. The spell creation in Daggerfall was the most robust of all the Elder Scroll games, as the spell creation systems in the later games were limited to a small variety of effects. I would remember creating a teleport spell, setting my target inside a store and then wait till night outside. Once it was night, I would cast my spell and get inside without needing to break in and I could take everything. Money and items were not a problem after that.
Also, if you take the time to read the various books, you can learn about certain rituals that fall on certain dates each year. FAQ's also have the information but it was a nice little touch most people didn't pick up on, and dates in general were removed from future titles.
