I have the main window with some input boxes and button for Calendar and also the main button to add a task. When I enter text in input boxes and click to choose a date my inputs refresh (I guess because the window.read() is called again since it opens another window for calendar). I want to keep do_not_clear=False for inputs so it fires when I press the main button but how to prevent it from happening when I press calendar button? If you need some more information please tell me, this is my first post.

IMO, there's no way to stop the clear action for the Input elements after calendarbutton clicked, you have to do the clear action by yourself, like

import PySimpleGUI as sg

layout = [
    [sg.Text("Name"),
     sg.Input(key='-NAME-')],
    [sg.Input(key='-DATE-', expand_x=True),
     sg.CalendarButton("Date")],
    [sg.Button("Add task")],
]
window = sg.Window("Title", layout)

while True:

    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break
    elif event == "Add task":
        # DO the job to add task, then
        for key in ("-NAME-", "-DATE-"):
            window[key].update("")

window.close()
