import ttkbootstrap as ttk  
from ttkbootstrap.constants import *  
from datetime import date  

my_w = ttk.Window()  
my_w.geometry("420x300")  # width and height  

dt2 = date(2023, 12, 30)  # start date  

de = ttk.DateEntry(dateformat='%Y-%m-%d', firstweekday=2, startdate=dt2)  
de.grid(row=1, column=1, padx=10, pady=20)  

my_w.mainloop()

Reading and displaying selected date on a Label on click of a button.

Ttkbootstrap DateEntry get selected date

import ttkbootstrap as ttk  
from ttkbootstrap.constants import *  
from datetime import date  

my_w = ttk.Window()  
my_w.geometry("520x320")  # width and height  

dt2 = date(2023, 12, 30)  # for startdate  
sel = ttk.StringVar()  

de = ttk.DateEntry(dateformat='%Y-%m-%d', firstweekday=2, startdate=dt2)  
de.grid(row=1, column=1, padx=10, pady=20)  

def my_upd():  
    l1.configure(text=de.entry.get())  # displaying date  

b1 = ttk.Button(my_w, text='Show date', command=lambda: my_upd())  
b1.grid(row=1, column=2)  

l1 = ttk.Label(my_w, text='Date')  # to display date here  
l1.grid(row=1, column=3)  

my_w.mainloop()

Reading and displaying selected date on a Label ( without button click )

The override in MyDateEntry works by redefining the _on_date_ask() method of ttk.DateEntry. When the date picker is opened and a date is selected, the original _on_date_ask() method runs first (super()._on_date_ask()), ensuring normal behavior. Then, the event_generate("<<DateEntrySelected>>") function is triggered, dispatching a virtual event that allows other parts of the program (like the label update function) to respond automatically. This eliminates the need for a button and enables real-time updates whenever a date is chosen.

import ttkbootstrap as ttk  
from ttkbootstrap.constants import *  
from datetime import datetime  

class MyDateEntry(ttk.DateEntry):  
    # Override function  
    def _on_date_ask(self):  
        super()._on_date_ask()  
        # Generate the virtual event  
        self.event_generate("<<DateEntrySelected>>")  

    # Function to return the selected date  
    def get_date(self):  
        return datetime.strptime(self.entry.get(), self._dateformat)  

# Create main window  
window = ttk.Window(themename='darkly')  
window.title('Calendar')  
window.geometry('300x400')  

# Label to display the selected date  
label = ttk.Label(window, text='Date: ')  
label.pack(pady=10)  

# Function to update label when a date is selected  
def update_label(event):  
    print(f'event: {event}')  
    date_object = event.widget.get_date()  
    print(date_object)  
    formatted_date = date_object.strftime("%A, %b %d")  
    print(formatted_date)  

    # Update the label with the selected date  
    label.configure(text=f'Date: {formatted_date}')  

# Use the custom DateEntry widget  
cal = MyDateEntry(window, bootstyle="primary")  
cal.pack()  

# Bind the event to the DateEntry  
cal.bind('<<DateEntrySelected>>', update_label)  

# Run the application  
window.mainloop()

All ttkbootstrap styles are applied using the bootstyle parameter. We can use all the avilable styles and apply to DateEntry.
DateEntry all bootstyle colours

import ttkbootstrap as ttk  
from ttkbootstrap.constants import *  
from datetime import date  

my_w = ttk.Window()  
my_w.geometry("700x200")  # width and height  

c, r = 0, 0  

for my_style in my_w.style.colors:  # List of styles  
    de = ttk.DateEntry(bootstyle=my_style)  
    de.grid(row=r, column=c, padx=2, pady=20)  

    c = c + 1  
    if c == 4:  
        c, r = 0, 1  

my_w.mainloop()

state

After creation of the DateEntry we can update the state option. It can take values : readonly, disabled or invalid.

de.configure(state='readonly')
#de.configure(state='disabled')
de.configure(state='invalid')

I found a solution so you don't need a button! Override the class and generate the event, since it isn't generated. import ttkbootstrap as ttk from ttkbootstrap.constants import * from ttkbootstrap.widgets import DateEntry from datetime import datetime class MyDateEntry(ttk.DateEntry): # override function def _on_date_ask(self): super()._on_date_ask() # generate the virtual event self.event_generate("<<DateEntrySelected>>") # function to return the selected date def get_date(self): return datetime.strptime(self.entry.get(), self._dateformat) window = ttk.Window(themename='darkly') window.title('Calendar') window.geometry('300x400') label = ttk.Label(window, text='Date: ') label.pack(pady=10) def update_label(event): print(f'event: {event}') date_object = event.widget.get_date() print(date_object); formatted_date = date_object.strftime("%A, %b %d") print(formatted_date) #global label label.configure(text=f'Date: {formatted_date}') # use the custom DateEntry cal = MyDateEntry(window, bootstyle="primary") cal.pack() cal.bind('<<DateEntrySelected>>', update_label) # run window.mainloop()
