PHOENIX — Sunday at sundown marks the holiest day on the Jewish calendar - Yom Kippur or Day of Atonement.
On Yom Kippur, people fast, pray, and reflect on mistakes they've made over the past year.
ABC15 spoke with Rabbi Mendy Deitsch from Chabad of the East Valley about what this holiday means to him and other who observe.
Rabbi Deitsch explained it's a time to make promises and goals to overall be a better person - and also a time of deep reflection.
"I make a resolution that I will live a better life," explains Rabbi Deitsch, "And that I won't do that thing I did, that transgression, speak gossip or whatever - and I'll use my mouth, my eyes, my lips, for the proper purposes."
Yom Kippur ends Monday at sundown when Jews gather with friends and family to "break the fast."
