Count the Omer

The Count the Omer action returns the phrase for counting the Omer on a given date.

This is useful when you want an automation or script to announce or display the daily Omer count, for example as part of an evening routine during the Omer period.

This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label. Instead, you provide the date and tradition to count for.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To count the Omer from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. From the search box, search for and select Jewish Calendar: Count the Omer.
6. Select the Nusach, and optionally set the Date, After sunset, and Language.
7. Select Save.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as jewish_calendar.count_omer. Because this action returns data, use response_variable to capture the result. A basic example looks like this:

action: jewish_calendar.count_omer
data:
  nusach: sfarad
  date: "2025-05-20"
  language: en
response_variable: omer

This counts the Omer for the given date and stores the result in the omer variable.

Options in YAML

Response data

The action returns the following data:

• message: The phrase for counting the Omer. Empty when there is no Omer count on the given day.
• weeks: The number of complete weeks counted.
• days: The number of days counted beyond the complete weeks.
• total_days: The total number of days counted.

For the example above, the response looks similar to this:

message: >-
  Today is the thirty-seventh day, which are five weeks and two days of the
  Omer
weeks: 5
days: 2
total_days: 37

Count today’s Omer in Hebrew

For a minimal call, provide only the required nusach. With no date, the action counts the current Hebrew day, taking the current time relative to sunset into account, and returns the text in Hebrew by default.

action: jewish_calendar.count_omer
data:
  nusach: sfarad
response_variable: omer

This returns a response similar to:

message: היום ארבעה עשר יום שהם שני שבועות לעומר
weeks: 2
days: 0
total_days: 14
