Know Your Timeline For Every Scene

I created a rough timeline.  I do it old school with paper and pen. 

Here It Is:

I drew a line in the middle of the page.

The left side is the major plot points

The right side is what happens and the time of day and weather.

It is very rough.  This is for my eyes only.  But now I know what day the book starts and the weather, and what day the book ends and the weather.  That is major to me.  My timeline is Thursday-Sunday

Your timeline my be months, years or centuries, but this gives you where months etc should go. 

Then as I write each scene, I will pay more attention to the time of day, the weather and the month of the year.  It will give you more depth in each scene.

What do you think?  Have you ever created a timeline?
