Alright, let's get started by creating a new base in Airtable. Once you've got that, make a table to store all your recurring tasks. You could call it something like "Recurring Tasks".

Now, let's configure your table with some key fields:

• Task Name: This will be a single line text field for the task's name.
• Due Date: A date field for when the task is due.
• Frequency: Use a single select field to specify how often the task repeats (Daily, Weekly, Monthly).
• Last Reminded: A date field to keep track of the last reminder sent.
• Next Reminder: A formula field to calculate the next reminder date based on the last reminder date and the frequency.

Here's an example formula for the "Next Reminder" field:

IF(
  AND({Last Reminded}, {Frequency}),
  SWITCH(
    {Frequency},
    "Daily", DATEADD({Last Reminded}, 1, 'day'),
    "Weekly", DATEADD({Last Reminded}, 1, 'week'),
    "Monthly", DATEADD({Last Reminded}, 1, 'month')
  )
)

Head over to the "Automations" tab in Airtable. Click on "Create an automation".

Choose "When record matches conditions" as your trigger.

• In the trigger configuration, set it to trigger when the "Next Reminder" is today:
  ```markdown
  {Next Reminder} = TODAY()
  ```

Now, let's add an action that will be executed when the trigger condition is met. Usually, this will be sending an email or a Slack message.

• Choose an action like "Send an email".
• Configure the email settings, including the recipient's email address, subject, and body. You can use fields from the record in the email body, like {Task Name} and {Due Date}.

Test your automation by clicking the "Run test" button. Make sure everything works as expected and that an email (or another action) is triggered based on the "Next Reminder" date.

Once the test is successful, activate the automation by toggling the switch to "On".

Don't forget to update the "Last Reminded" date each time a reminder is sent. You can do this manually or set up another automation to update the "Last Reminded" field with the current date once the reminder email is sent.

By following these steps, you can set up and manage automated reminders for recurring tasks in Airtable.
