tefillin times based on zip code in USA

Hi, thanks for contacting Hebcal. Although the underlying Hebcal algorithms support calculation of halachic times (zmanim) we have not built a website interface for calculating times. We do plan to eventually offer this feature but do not have a fi date to share.

We do have an experimental zmanim feed which requires some technical comfort editing a URL and offers only very limited customization options

Consider MyZmanim.com as an alternative website that offers lots of customization
