I have been looking at the website https://thenightsky.com and wanted to create a star map my self, from a specific place on a specific date. Where would I be able to find this?
As mentioned in the comments, download and install the free app Stellerium. You can input the location and date of interest and it will display the sky. The app is like having your own planetarium. There is another similar app named Celestia. It is also free. I would recommend Stellerium.
