Custom Colour for Weekends in Google Calendar

Image from store

Description from store

>>>>>>>>>>>>>>>>>>> LET'S GO DARK! <<<<<<<<<<<<<<<<<<<<<<
Works with Calendar's DARK MODE too! The extension AUTOMATICALLY detects dark mode and renders in a dark fashion the colours you chose! Yay! :)
>>>>>>>>>>>>>>>>>> Important NOTE!!! <<<<<<<<<<<<<<<<<<<<<<
If it doesn't work, before giving a low rating contact me via the Assistance Channel or via Mail: I will work with you to solve the issue!
>>>>>>>>>>>>>>>>>>>>>> DONATE! <<<<<<<<<<<<<<<<<<<<<<<<<
If you LIKE THIS EXTENSION, please consider a DONATION (LINK is in OPTIONS PAGE or you find it if you RIGHT CLICK over extension icon!). A coffee will be just fine! :D

Choose custom colours FOR EACH of your week's days! Those days will be coloured with your custom background colours, highlighting your calendar in ALL "views" of NEW Google Calendar (2018 and further)!

At first install, you will be automatically redirected to options page, where you will have to choose your Google Calendar's page language (MANDATORY), and the colours for all your days.
If you prefer NOT to highlight a day, simply leave it WHITE. Choose light colors also for dark mode, the extension will automatically detect DARK MODE and darken your colors (leaving black the non-highlighted days).

In OPTIONS page you can now donate me a coffee, too! :)

NOTE: sometimes while working it could stop highlighting the weekend columns; in that case, try to click on an empty space on the calendar or press F5 (refresh page) and the weekend columns will be correctly light up again!

Roser Urreizti 2025-07-18: I was fuming as it wasn't working until I noticed that I had a different language set in the extension than in my Google Calendar. Fixed that and it worked so nicely! It's really useful and simple to use (especially for non-multilingual people... 🤦🏽‍♀️).
Ryan Preece 2025-07-15: Simple and effective. Exactly what I was looking for. Thank you!
Danny Lyubenov 2025-06-05: Just what i needed, but my OCD is kicking in because the names of the week gets slightly cropped once i enabled the extension :(
Jérôme Alteyrac 2025-02-06: just what I wanted !
Paul Chipperfield 2024-11-13: I think this should be great but like an earlier post the colours only highlight the top and not the whole day. 2.1.4 installed today. Update.....Yes it works but only in week view, not in month view. Further edit.November 2024. Works beautifully now. Thank you Riccardo (Slow response due to hospital).
nyx f 2024-08-09: Incredible app and user support! It's simple, elegant, and flexible. I appreciate having complete control of the colors. This is an indispensable tool for anyone who needs see the day of the week as quickly as possible. I am prone to making scheduling mistake and adding custom color coding has changed my workflow completely. I am not exaggerating when I say that I can't function without this app. In addition, I really appreciate the dev's attention to detail and eagerness to address even the most minor of bugs. He responds quickly and provides clear instructions. Thanks again Riccardo! NF
Vinícius Pimentel Couto 2024-05-23: Great extension! It stopped working once and I noticed how much I missed it. Thankfully Riccardo was really helpful and quickly updated the extension with a fix, as well as provided a workaround so I could get it working while the update didn't get pushed to me. First donation due to an extension, this is one of those things that should be default in the calendar.
Elodie Bonckaert 2024-03-30: Thank you
John Wagner 2024-03-26: Only puts a tiny strip of color at the top of the Saturday and Sunday columns. It doesn't shade the actual boxes for each Saturday and Sunday
Megan Lee 2024-03-04: Used to work great, but now doesn't show up, even if I remove from Chrome and reinstall. Only shows up as a itty bitty strip of colour at the top of my Google Calendar, but not enough to highlight the weekend column by a long shot. Please fix, I want to use it again!
Naty Rossi 2024-02-02: it doesnt work anymore. I tried to reinstall a couple of times. It just stop working

Anonymous 2023-04-10: Works great! I only have one problem, but it's my fault (lack of knowledge): I can't find how to get to the settings to make a change. The only solution I found is to remove it, install it again and then the configuration page appears automatically. Excuse my ignorance! But it's just what I was looking for!
lee marco 2023-02-10: sorry, but it doesn't work for me too. I tried to clean the cache and cookies, and reinstall again and again. Well, finally I GIVE IT UP NOW........

Steven Harriss 2022-12-01: I just can't seem to get it to work - I've changed the settings to every combination I can think of but nothing ever changes on the calendar - a complete waste of time. I really can't think what I'm doing wrong as there isn't much to configure.

Amitab Sood 2021-12-19: Thank you for this extension! I have problem though. The extension keeps forgetting the settings for Language and Weekenddays and thus will not show Weekends in the calender. Right after installation it did work and also on some rare occasions it shows up, but then it forgets it again. When I set the settings again on optionspage and then close and open the optionspage it has forgotten the settings already, most of the times. I can not figure out the pattern, when and when not it will work. Deleting and reinstalling did not solve the problem. I have about 10 other (productivity) extensions, and never have any proplems there. Do you have any Ideas, what I could try?

Dottie Bowles 2021-04-26: I've only started using this extension and I just love it! It works seamlessly and is very useful! I would love to be able to choose a color for any of the days, or each day, like if you could have each day of the week have a color selector. For my case specifically; I would want the weekends and Wednesday to all have the ability to change color. Although I'm sure others would also love to be able to set any color to any day. -- Such a useful extension! :)

Guy Marais 2019-09-06: This is pretty convenient, but it could be very much improved by being able to see Sat/Sun in a customised view. I use the calendar showing the next 7 days, and I'd find it extremely useful if the weekends could also show. In this case, I'd definitely give it a 5-star rating. Think about it for the next update. Thanks! Edit: It works now: 5-star! Excellent job!

Yaab (Amir Yabo) 2019-09-05: Used to work fine. Starting from new update (Sep 2019) week and month views are handled ok, while customized view (2 weeks in my case) don't show weekend colors.

Robert Andrews 2019-07-23: This is great, very useful. Has even got me thinking about a few enhancements... - Colour-picker. - How about colour-coding other days? In fact, how about colour-blocking particular time windows *within* days? - eg. 9am-5pm is a work zone and, therefore, red.
