We've added a feature for IFTTT and other APIs where you can append ?yto=1 to a Hebcal URL so the events that show up are only yom tov holidays.

For example:

https://download.hebcal.com/v4/CAFAAWoBc4ABAZgBAaABAQ/hebcal.ics?yto=1

For Gregorian year 2023, for example, only the following holidays would be considered Yom Tov:

Tisha B'Av is the Ninth of Av. It is a fast commemorating the destruction of the two Temples.

Tu B'Av is a minor Jewish holiday of love. It is observed on the 15th day of the Hebrew month of Av.

Thank you for this suggestion!
