# Calculating date of heliacal rising of well know stars using javascript

(Asked by: username_0 on 2022-05-11)

I am pretty new to astronomy, and would like to find a way to calculate the date of the heliacal rising of well know stars form a given location using javascript, so that the dates can be rendered in a table on a web page.

Are there any existing javascript libraries that will allow me to do this? And if so how would I go about using said library to achieve my objective?
