Adar is the sixth month of the Jewish calendar, and it is associated with Shevat, the eleventh month. Shevat followers are those who observe the traditions of the month, which include celebrating Tu Bishvat, a holiday that marks the beginning of the new year for trees. Additionally, Shevat followers may also observe the custom of eating dried fruits and nuts on Tu Bishvat, as well as engaging in other activities such as planting trees or donating money to environmental causes.
