How do I create a date picker in tkinter?

Question

Is there any standard way tkinter apps allow the user to choose a date?

Answer 1

The answers here provide most of what you asked for, but I felt none of them were completely satisfying. As a Tkinter newbie, I needed more hand-holding. My complaints:

1. Assuming I want the calendar to default to a 2012 date rather than today's date,
2. Not returning the result as a variable for future use,
3. An unnecessary top layer menu before getting to the calendar, and
4. Not cleaning up the windows and exiting mainloop after a selection has been made.

So with gratitude to the previous answers which helped me immensely, here's my version.

def get_date():
    import tkinter as tk
    from tkinter import ttk
    from tkcalendar import Calendar, DateEntry

    def cal_done():
        top.withdraw()
        root.quit()

    root = tk.Tk()
    root.withdraw() # keep the root window from appearing

    top = tk.Toplevel(root)

    cal = Calendar(top,
                   font="Arial 14", selectmode='day',
                   cursor="hand1")
    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=cal_done).pack()

    selected_date = None
    root.mainloop()
    return cal.selection_get()

selection = get_date()
print(selection)
