Specifically time management for the day, not for longer timeframes such as weeks and months. They all are based on a visual representation of a day and can be as creative or as plain as you would like.
This is the most straight forward representation of time that I have used. I used it for a long time and loved how it gave me a detailed view of my day at a glance. I first saw this idea from Dee over at Decade Thirty. The basic concept is you draw a vertical number grid for the day and often using color sections next to it mark off sections of your day.

This is what I am currently using. (Specifically this document here)
The Chronodex was created by Patrick Ng. It is a similar concept but in a tighter/smaller package. It is very expandable which is something that I love about it. I have successfully used it for planning a simple day for myself to handing my whole families schedule on it. This expandability is what makes me stick with it even if there is easier options.
Just a simple google search for Chronodex will bring up more examples than you could get through in a lifetime.
A simpler version of the Chronodex was created by Kent from Oz and is called the Spiraldex. It is based off of the spiral shape that is used in the Chronodex but makes it visually more obvious in the Spiraldex.
If you like the idea of the chronodex but not the level of difficulty this might be the perfect option for you. For more information on the spiraldex check out Kens post here
These three are great visual representations of your day. That process of seeing your day planned out has really helped me to see how I am using my time and adjust accordingly. I encourage you if you use analog means to track your day to give one of these a try.
Do you have a different way that you track your day?
