I did a quick google search after reading this because I have an app that tells me when golden hour starts, there are several apps and websites that can tell you when blue hour starts.
An app is a good start, but it's hard to really know exactly when and for how long the sky will looks its best. It really depends on the altitude of the clouds that evening. High clouds are awesome since the sun will dip below them earlier and they will light up red (Not my pic: https://farm4.stat...6_47e7e12fb1_b.jpg
). With low thick clouds, you may not even get to see the sunset. It's best to get set up before hand and wait out the sunset to see what happens. I rarely motivate myself to go do this, but it makes for a nice night if you get setup and have a nice view.
