python - 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

In case anyone still needs this - here's a simple code to create a Calendar and DateEntry widget using tkcalendar package.

pip install tkcalendar (for installing the package)

try:
    import tkinter as tk
    from tkinter import ttk
except ImportError:
    import Tkinter as tk
    import ttk

from tkcalendar import Calendar, DateEntry

def example1():
    def print_sel():
        print(cal.selection_get())

    top = tk.Toplevel(root)

    cal = Calendar(top,
                   font="Arial 14", selectmode='day',
                   cursor="hand1", year=2018, month=2, day=5)
    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=print_sel).pack()

def example2():
    top = tk.Toplevel(root)

    ttk.Label(top, text='Choose date').pack(padx=10, pady=10)

    cal = DateEntry(top, width=12, background='darkblue',
                    foreground='white', borderwidth=2)
    cal.pack(padx=10, pady=10)

root = tk.Tk()
s = ttk.Style(root)
s.theme_use('clam')

ttk.Button(root, text='Calendar', command=example1).pack(padx=10, pady=10)
ttk.Button(root, text='DateEntry', command=example2).pack(padx=10, pady=10)

root.mainloop()
