As @Andrew_Johnson1 hints, automatically generating records takes you out of pure Airtable functionality, although it can be done with assistance from a middleware service (Zapier, IFTTT, etc.) or a manual action.
Alternatively, you could create a formula field that combined a set month and day with the current year to create a rolling due date. The ‘completed’ tick-off becomes a little more complicated, though, as you would either have to timestamp the date and time the task was completed (which currently requires the creation of a linked record to hold a persistent timestamp) or manually clear the completed tick at some point prior to the task becoming due again.
