New Year Message after Countdown

Tkinter window showing countdown in Hour Minute and second left for new year with New year message

To test the scirpt we can comment the line declaring dt2 inside the function. This will use the variable dt2 of main script. The value of dt2 is taken as 10 seconds more than the current time so the countdown will start ( or last ) for 10 seconds. After 10 seconds we can check the New year message.

Here is the complete code.

from dateutil.relativedelta import relativedelta
from datetime import datetime

import tkinter  as tk 
from tkinter import ttk
my_w = tk.Tk()
my_w.geometry("405x170")  
from time import strftime
dt=datetime.today()
# Below line is used for testing by adding 10 seconds to present time
dt2=datetime(dt.year,dt.month,dt.day,dt.hour,dt.minute,dt.second+10)
def my_time():
    dt=datetime.today()
    # comment the below line to test the script with 10 second gap
    dt2=datetime(dt.year+1,1,1,0,0,0) # Date and time for new year
    dt3=relativedelta(dt2,dt) # time left for new year 
    h=dt3.hours
    m=dt3.minutes
    s=dt3.seconds
    #print(h,m,s)
    if(h>0 or m>0 or s>0):
        t_string = str(h).zfill(2)+ ":" + str(m).zfill(2) +":"+ str(s).zfill(2)
    else:
        l1.config(font=('times',40,'bold'))
        t_string="Happy New Year"
    l1.config(text=t_string)
    l1.after(1000,my_time) # time delay of 1000 milliseconds 
	
my_font=('times',76,'bold') # display size and style

l1=tk.Label(my_w,font=my_font,bg='yellow')
l1.grid(row=1,column=1,padx=5,pady=25)

my_time()
my_w.mainloop()
