Day-O is a simple menu bar app that displays the exact time and date in various formats. Unlike the default clock coming with Mac OS X, this program provides you with an integrated calendar which you can glance through while making new appointments.

This menu bar app is very simple to use as it provides you with an intuitive interface and easy-to-configure settings. You can select your own time and date format by going to the Preferences menu and entering the pattern that matches your needs (you can find format pattern info by clicking the "?" button).

A disadvantage of Day-O is that it doesn't allow you to schedule meetings, set project deadlines or keep track of daily tasks while using the calendar. Still, the program's goal is to offer you a customizable menu bar clock to use on a daily basis and not a complex calendar tool.

As for the rest, the application proves to a reliable solution as it keeps you informed about the exact time and date according to your time zone. Plus, you don't have to pay to use it; therefore, I can't find any reason why you shouldn't give this program a try.
