How can I show weeknumber in the taskbar in Windows 10?

Question

Is there a way to show the week number in the taskbar in Windows 10? I prefer it to be integrated in the Windows clock application that is showing in the taskbar anyway - directly or by left/right click. But at the moment I take any workaround including 3^rd party software.

My current workaround is to open the calendar via the start menu (with week numbers enabled). So I don't need another solutions that opens a window which I manually have to close again.

Note: I made a second question in regards to Windows 11: How can I show weeknumber in the taskbar in Windows 11?

Answer 1

You can use White-Tiger/T-Clock. It supports Windows 10 since version 2.4.1. You can download the latest release here. Just extract then run, there's no installer

After starting T-Clock you need to enable its calendar first right clicking on the clock > T-Clock options. In the Miscellaneous tab check on Use T-Clock's calendar and Show week numbers

If you want official support please vote on Windows 10's Feedback Hub (installation of the Feedback Hup App is necessary). Many people have already reported that: https://aka.ms/AA5mk4r, https://aka.ms/AA7ujey, https://aka.ms/AA7ubxo

One option if you're really struggling, would be to create a small little application that is configured to run at startup that creates a notification tray icon.

If you download Visual Studio 2019 Community version, you could create a new C# .Net Forms application with the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Globalization;

namespace WeekCounter
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MyCustomApplicationContext());
        } 
        private static void MessageBox(string v)
        {
            throw new NotImplementedException();
        }
    }

    public class MyCustomApplicationContext : ApplicationContext
    {     
        private NotifyIcon trayIcon;

        public MyCustomApplicationContext()
        {
            // Initialize Tray Icon
            trayIcon = new NotifyIcon()
            {
                Icon = WeekCounter.Properties.Resources.icon,
                Text = "WeekCounter",
                ContextMenu = new ContextMenu(new MenuItem[] {
                new MenuItem("Exit", Exit)
            }),
                Visible = true
            };

            trayIcon.MouseMove += new MouseEventHandler(notifyIcon1_MouseMove);
        }
        private void notifyIcon1_MouseMove(object sender, MouseEventArgs e)
        {
            CultureInfo myCI = new CultureInfo("en-US");
            Calendar myCal = myCI.Calendar;
            CalendarWeekRule myCWR = myCI.DateTimeFormat.CalendarWeekRule;
            DayOfWeek myFirstDOW = myCI.DateTimeFormat.FirstDayOfWeek;
            trayIcon.Text = "Time: " + DateTime.Now.ToString("MM/dd/yyyy h:mm:ss tt") + "\nWeek: " + myCal.GetWeekOfYear(DateTime.Now, myCWR, myFirstDOW);
        }

        void Exit(object sender, EventArgs e)
        {
            trayIcon.Visible = false;
            Application.Exit();
        }
    }
}

Note: Under the "Resources" for the project you can add a suitable ico file as an icon resource. It is referenced in the code as "icon" so the resource will need to be named that:

Icon = WeekCounter.Properties.Resources.icon

You could ensure the exe is run at startup by adding a reference to it under the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
