Hi, thanks for using Hebcal and thanks for the question!
Since one year ago (August 2020) our sunrise/sunset algorithm is based on NOAA. There is a little more detail about our implementation here:

Hi, thanks for using Hebcal and thanks for your patience!
As you have noticed, calendars exported from Hebcal to Apple or Google Calendar or other services that support iCalendar subscription feeds are typically “perpetual”. That is, they contain events for the current year (Gregorian or Hebrew) plus some number of years into the future. Our calendars typically have 5 years of events (current year plus 4 years into the future).
Subscription feeds are the recommended approach because they are easier to manage (with different alarm options, etc) and because Jewish calendar events can be displayed in a different color.
If you'd like to capture historical holidays from Hebcal and merge them into your personal calendar, this can indeed be done with a little bit of additional export/import effort.
You can visit our https://www.hebcal.com/hebcal page and enter a past year (for example 2015) in the form and then click on the Create Calendar button.
On the calendar results page, click the Download button and note the "Alternate option" text at the very bottom of the Download dialog box.
Alternate option: Download hebcal_2015.ics and then follow our Google Calendar import instructions.
If you click on this link, it will download a file (not a subscription feed) with exactly one year of events, which you can then import into your preferred calendar application.
Hi, thanks for using Hebcal. We're sorry to hear that you're having some difficulty with the triennial leyning spreadsheet
We recommend that you download Comma Separated Value (CSV) file from Hebcal and import into Microsoft Excel or some other spreadsheet program. We don't recommend importing these CSV files into Outlook.
We've changed Hebcal to match how Google's Holidays in Israel calendar displays the holiday.
