I have this old and slightly buggy vim plugin [1] which uses py-ephem to determine the correct moment to switch themes every day. It's been quite a while since I've used vim and I don't maintain this, but you may want to chech it out. BTW, if there's anybody that wants to take over it, please contact me via a github issue through the repo below. [1] https://github.com/cadadr/vim-sunflower https://github.com/cadadr/vim-sunflower
