Kivy How to add changing Dates in Spinner (Dropdown)

Question

I need the Spinner Dropdown to have values containing- Present day's Date (whichever day the user is opening the app)...+ the next 10 Dates from the present day. (Note- It should update automatically)

For example, if present date is 18/8/2021 I need the dropdown to show:-

---

| Select Date ^ |

---

| 18/8/2021 |

| 19/8/2021 |

| 20/8/2021 |

| 21/8/2021 |

| 22/8/2021 |

| 23/8/2021 |

| 24/8/2021 |

| 25/8/2021 |

| 26/8/2021 |

| 27/8/2021 |

| 28/8/2021 |
