Sunrise/Sunset

My weather channel app on my iPhone had it. But my droid it does not

 

It may not be as accurate but I always have a calendar with the sunrise and set on it. But I also make notes about different things on it to cause its easy to refer back to if asked about that event.

 

When the cops leave the dunkin donuts, its sunrise....when the lot lizards come out, its sunset lok

 

About 2 hrs after the roosters wake you up. Look west for the red sky at night

 

This book can be found at a good amount of the larger truck stops, or here http://showcase.netins.net/web/directory/book.html
It has sunrise/sunset charts for every sate in it. It's not as convenient as a GPS or an app as far as pinpoint accuracy goes, but it's what us heavy haulers have relied on for years before we got all hi tech.
Weatherbug app, I believe it is both Apple & Droid available, also has it for your location.

 

I ask Siri. Probably the only time I use it on my iPhone besides texting and driving.

 

Siri will answer if you have a Bluetooth so you can use her hands free lol. She brings a whole new level to what you can do while driving. I normaly use my rand mc gps tho
