Hoshana Raba is an usual holiday. Like Purim and Erev Yom Kippur, it is a holiday without restrictions. That means that it’s okay  to drive, cook, use electricity, make phone calls, send emails,  etc. but  is a day permeated with holiness, repentance and prayer

According to the Kabalah on  Hoshana Raba  the judgment which was rendered on Rosh Hashana and inscribed on Yom Kippur is sealed today. As we do on Purim and before Yom Kippur, we eat kreplach, to signify Hashem‘s mercy encasing His judgment

Ukrainian Jews would commemorate Hoshana Raba with   hallot baked in the shape of a hand open  to recieve (pitka or kvitel) containing a good judgment. The greeting for this day is “Have  a Gite Kvitel (a good note)”

Here’s a picture. Best wishes for a Gite Kvitel!
