If you don't want to scrape a Web page, or want this information when a network is not available, the hdate package will do (referenced from: https://unix.stackexchange.com/a/527031).
Here is an example for Topeka, KS:
$ hdate -l N39.034722 -L W95.695556 -s -z -5
Saturday, 23 September 2023, eve of 9 Tishrei 5784
sunrise: 07:10
sunset: 19:18
hdate: ALERT: The information displayed is for today's Hebrew date.
Because it is now after sunset, that means the data is
for the Gregorian day beginning at midnight.
