This project has started to celebrate the yearly International Men's Day!
Unfortunately, Google decided to only celebrate the International Women's Day by replacing the logo.

Installing this script exchanges the google logo by a custom holiday logo.

You'll need a browser extension such as violentmonkey (open source ftw) and import the script.
For violentmonkey on Chromium it's the following steps.
Click on:

1. Violentmonkey icon in browser
2. Open dashboard (cogwheel)
3. New (plus)
4. Install from URL
5. Paste raw js URL: https://raw.githubusercontent.com/delinsyl/happyinternationalmensday/master/source.js
6. Ok

Enjoy!

It should work for google with any top level domain.

Thank you very much, reddit user /u/not_jainam, who gave me the rights to use his beautiful logo for this public project.
