How to set the calendar widget to current date

[scratchmyhead]

I have a calendar widget in my program that I copied from google. It works fine but how do I set it to current date each time the calendar is opened? Below is the code.

def example1(event):

    top = tk.Toplevel(root)

    def print_sel():
        print(cal.selection_get().strftime("%m-%d-%Y"))
        print(now.strftime("%m-%d-%Y"))
        departe.delete(0, END)
        t = departe.get()

        print(t)


        dayse.delete(0, END)
        departe.insert(0, cal.selection_get().strftime("%m-%d-%Y"))
        t = departe.get()
        j = arrivale.get()

        g=int(t[3:5]) - int(j[3:5])
        dayse.insert(0, g)

        cal.destroy()
        top.destroy()
    cal = Calendar(top,

    font="Arial 14", selectmode='day',
    cursor="hand1",  year=2020, month=5, day=3) #Here it is set to certain date but I want current date each time it is opened.
    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=print_sel).pack()
    #cal.bind("<Button-1>", quit())
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)
