Yay! The new NASA Dial-A-Moon phase calculator for 2019 is out!
Oh, I so love this thing. You enter a date and time (in UTC) and it shows you what the Moon will look like. The image generated is based on images and elevation data taken by the Lunar Reconnaissance Orbiter, which has been mapping the Moon since 2009. The calculator is a fun way to see what phase of the Moon will be visible at any time, which personally is useful for me when I need a good image of the Moon for an article.
