For a few years I’ve gotten used to using Alpha Clock, which is a small taskbar utility which gives you more options than the standard Windows clock you always see in the bottom right of the screen. You can change the format of the clock, show the date, have different skins etc. But that free version has ran out now, so I’ve eventually found this one which does a similar job: TClock2
To be honest, the only reason I use it is for the date. I’m useless with remembering the date, so it’s just easier to look at the date in the corner of the screen – rather than go clicking around or whatever.
I find it handy, someone else might do too. There are decent skins on there which will make it blend into XP if you’d rather keep it quiet in the corner, not drawing attention to itself.
