  • (2022-05-02) Shirla Brown-Onuchukwu: I am so frustrated. It just doesn't work!!!!! I have tried and tried, read reviews, instructions...everything. This app just doesn't work. Low-key frustrated
  • (2022-04-03) Andrea Jones: I don't understand how to add the images. I've tried every type of url and none works. Unistalled.
  • (2022-03-01) Johan Roman: Cual debe ser el tamaño de la imagen en pixeles, porque pude una foto y solo se ve la mitad en google calendar
  • (2022-02-21) Liana Flores: i love it!!! my only minor issue is that if dark overlay is on, the text is white over a white background when you're putting something on the description
  • (2022-02-19) Truc Nguyen: I have never found a more confusion extension. I submitted the URL of my image but it does not load. Tried multiple links, still doesn't work. It will only shows the pre-selected images that they have. Maybe it's a bug but I got too frustrated and uninstalled. Maybe you can let me know once you fix the issue. UPDATE: I was able to get it to work thanks to Patrick's help.
  • (2022-02-12) Nourhane Atmani: I can't upload a screenshot, but whenever I try to custom the background, it shows a screen with a chinese writing and nowhere to edit, add a link or change the gcal background.
  • (2022-02-11) Bridget Stahovic: THANK YOU! I needed something, anything, other than the stark "im doing work right now" white bg, and I love the stock that you put. Though I have a question, if I wanted to add my own, what aspect ration of the image would be best to use? Thank you again, great "quality of life" style add-on.
  • (2022-02-10) Kayla Stevens: I like this extension! It makes the google calendar a lot prettier. I was wondering if anybody had figured out how to stop it from zooming in too much and going blurry when you add your own image, or if there is a preferred resolution for these images?
  • (2022-01-24) Nicole Silva da Costa: I don't know to exchange the pic
  • (2021-12-27) Louise Raskin: it doesn't work?
  • (2021-11-09) Carol Gallmeyer: I love the concept but after a couple weeks of using this, suddenly my event details were not legible when I popped open a box. All the text had turned to white and I couldn't read anything. Upon turning off the plugin, everything appeared normal again.
  • (2021-11-01) Nicole Jimenez: It has started to work again after the image problems, however, I noticed that ever since the image came back, I have had some problems with Chrome. It started to close itself, to check if it was the extension, I had to delete it for a couple of days and after that, the problem was resolved. Please fix this problem because I love this extension.
  • (2021-11-01) Lydia Hamilton: Works like charm! After sending one too many emails/calendar invites from my work gmail instead of personal, I needed to differentiate the two. CLUTCH!
  • (2021-10-21) Phoebe Pham: It worked well for a few months, but now it no longer loads anything, and it removed the image from my background.
  • (2021-10-13) Abi Hicks: Stopped working today :( Was great! But now there is no image, and when I click on extensions it says on the menu that it doesn't need access to the page despite it saying it has access to calendar.google.com when I click on the actual extension. Hope this is helpful in fixing the issue! EDIT: issue has been fixed! its back and working better than before!

  • (2021-10-09) Ammar Danish: I add the extension but it seem like it doesn work?
  • (2021-10-09) Albert Ramos: Was great while it worked, but looks like it recently broke.
  • (2021-10-09) Karen Rothstein: Don't waste your time. Doesn't work for me.
  • (2021-10-08) Bob: Great extension. Too bad it stopped working this week. Hope to see it working again.
  • (2021-10-07) Olga Kharlip: The extension was perfect up until today Oct 7 2021, because it stopped working. Please fix
  • (2021-10-07) JERRA JOY AGRAVIO: the extension seems to not be functioning anymore. can someone help us? we really enjoyed this extension
  • (2021-10-07) Siti Munirah Kamaruzaman: ext was working wonderfully well and awesome, until like a week ago. it seems like no solution i can refer to. Now my calendar back to dull. can developer do somthing?
  • (2021-10-07) Rebeca B.: Unfortunately, it suddenly stopped working for no obvious reason.....
  • (2021-10-06) Rens: It seems that as of today (October 6, 2021) the extension stopped working. Can I please request you update it so it works again! Just discovered this extension today and I was very excited about that.
  • (2021-10-06) Alma Albarea: Pues el primer día iba muy bien, pero hoy de repente me ha dejado de funcionar en mi navegador (Opera GX). He intentado desinstalar y volver a instalar de nuevo, pero no se arregla. Si solucionan que no funcione en otros buscadores, le pondré 5 estrellas encantada, porque la verdad es que me animaba mucho el día <3
  • (2021-09-23) sulfatique: doesn't work for some reason :(
  • (2021-09-08) Denise P: Doesnt work for me :(
  • (2021-08-22) Princess Areo: it's good to have but it's not perfect. The picture is a little blurred so you can't see the whole picture. If I have my calendar in Month I can't see the days properly because it's in white and I can't change that. Took me a while to look for a good background that let's me see color and still read everything.
  • (2021-02-20) Aba DH: This extension is especially helpful now that it seems Google has disabled themes for the calendar. Thanks!
  • (2020-11-17) S L Scheets: So long as you have an img url, it is awesome. No upload support I can see. Make sure to refresh after applying changes. Recommend pixabay.com if you are looking for free img url's.
  • (2020-08-17) Brooklyn Harris: I love how easy this is, but no matter what I do it only shows the one picture as a background. I cannot get it to show the rest of the months as I flip through my calendar
  • (2019-12-09) James Giotta: Adding the background image is awesome. However, since I am unable to change font color, most images it is hard to read the calendar. I guess I just have to find the right image to allow all text on the calendar to be easily read.
  • (2019-10-17) Napstablook: I added a gif image of snow falling and it actually works on the background of Google Calendar! I love it! Thank you!
  • (2019-08-21) I wanted a way to add a touch of personalization to my Google Calendar, since we are checking it so many times a day at work. I came across Custom Calendar Background. After first downloading, I was pretty confused and didn’t think it was going to work. I didn’t see any change in my Google Calendar. I checked out the “Support” tab from the Custom Calendar Background download page and was sort-of led in the right direction. Someone explained that there would be a new circle button, however, that was not the case for me. After searching for a button, I found a button with no outline that simply said “image”. The way it is set up lets you either choose an image for each month or choose a single image. You cannot upload from your computer however. You have to search and find a photo you like on the web and get an image link and then paste that in. It took me a couple of tries to find one that looked fine. Overall, this tool did improve the look and feel of my calendar. I think it just needs updated documentation and possibly a way to upload from your computer.
  • (2019-03-23) Doesn't work.
  • (2019-02-06) Mattias: Does anyone know what aspect ratio / resolution I need to add so photos won't blur? I tried to use a hubble photo of the Pleiades, but it just wound up zooming in and cropping it as a blurry photo.
  • (2019-01-17) S H: I love it but wish there was a way to not have that haze covering the pic, I want to see my Hubble pic in all its glory.
  • (2018-11-07) Michael Smith: Fantastic extension. Really brightens up the bland white background with any picture that you feel is typical of the current month. Thank you for allowing me to adjust my calendar backgrounds to suit the seasons of the year.
  • (2018-07-18) Mark Rubensohn: This is wonderful. It has resolved the new Google calendar problem that I could no longer download my background image. Once installed go to any image , Right click, Copy Image Address and Paste it to the current month of your calendar, save and Whala!!!
  • (2018-04-21) Lumen Garden: It takes some attempts, but using google photos to get the image URL did the trick. Thanks!
  • (2018-03-04) Marianne Tierney: I managed to get it working :) makes my calendar look much nicer and more individual. Thankyou!
  • (2018-02-26) Nada Wassef: I love this as well but can someone HELP me make this https://calendar.google.com/calendar/r/ the default that open when i click on Calendar icon through gmail? can this happen? please let me know
  • (2018-02-14) Charles Roberts: Doesn't work on Mac OS Chrome. Wish it did because I HATE THIS WHITE BACKGROUND!
  • (2018-02-11) Nice Lilas: Excellent et ce serait super d'ajouter d'autres images de fonds d'écran !! Merci 02/2018 super les fonds d'écran mensuels ++++++ Merci !
  • (2018-02-10) Cyndi Olvera: DOESNT WORK
  • (2018-02-09) Roger H. Charles: This is for those who hate the blurry "new" look of GCal. With the right image, you can get more definition in the display of events. Experiment.
  • (2018-02-08) Lauren Rankin: Thank you so much for developing this, I absolutely love it! It did take me a few tries to get it right (user error)—but as it says in the description, I needed to access it through the calendar.google.com/calendar/r/ URL, not my old bookmarked link. Thanks again!

  • (2022-03-18, v:1.0.8) Lignail Chacon: Imagenes pixeladas
    Hola! Primero hacerles saber que amo tener esta opción en mi calendario. Desde que descargué la extensión, todas las imágenes que pongo se ven pixeladas y no me permite acomodar si quiera cuando se coloca solo una esquina de la foto. Me podrían instruir en esto? Gracias!

  • (2022-02-19, v:1.0.7) Dayton Livingston: Feature Req: Different pic/color based on profile
    I don't know if this is even possible, but I was hoping to find a tool to visually distinguish my work calendar from my personal calendar. I know I can merge them & etc. but I don't want that. I need to keep them separate, and color coding the actual background would be extremely helpful in that. If not possible, or beyond the scope of your project, I fully understand, and appreciate your time. Thanks!
  • (2022-02-12, v:1.0.6) Nourhane Atmani: I downloaded the extension today, and it won't work (error page)

    Hello! I just downloaded this extension today, and I love it however now I don't have the ability to click and drag meetings that are 30 minutes long. The curser changes to one that has an up and down arrow, only allowing me to change the duration of the meeting and now drag it to a different day or time. When I turned off the extension, it worked fine. Can someone please help?!

  • (2021-11-30, v:1.0.4) Aleksi Pälä: Problem when using working hours
    Hi, I just started using this extension today it is great on most parts and easy to use. I have found one bug or problem with it. When I am looking calendar of one of my collegue (search for people) who is using "working hours" feature, the non working hours are shown in default colour ( white with grey stripes). I am using color background feature with pretty dark colour so the white really pop ups. I would really appreciate if you could look into this problem and make the extension even more better. Thanks - Aleksi

    Hi! Do you have some suggestions regarding resolution or sizing of photos to prevent blurriness? Great calendar extension anyway :) Thank you
  • (2021-11-10, v:1.0.3) Mr. B.: Light/Dark Overlay Issue
    As of yesterday (11/09/2021), when I would single click on a calendar entry, I could no longer see the details of said entry in the pop-up box. I found that it was due to a white background with white text when trying to select/highlight anything within the box. I further discovered that the only way (that I can find, anyway) to remedy this is to change the extension settings to a dark overlay rather than the light overlay that I've had it set on since you got this back up and running. It was working fine on the light overlay until yesterday. The dark overlay makes certain things a bit more difficult to see or read. Your help and/or input would be greatly appreciated. One last thing, I turned off the extension to utilize Google's lovely stark-white background, and even though the pop-up box is still white, the text now appears there in black as it should. Thank you in advance.
  • (2021-11-09, v:1.0.3) Jeff S: invisible text in one-click quick view
    Hi - I really like the extension, but it seems the recent update makes the text in event details turn white in the one-click quick view, thus the text (everything but the event title) is invisible. To see the text I now need to fully open an event or highlight it with the cursor. The quick view text does become visible again when the extension is disabled.
  • (2021-11-01, v:1.0.2) Nicole Jimenez: Calendar problem
    I noticed that ever since the image came back, I have had some problems with Chrome. It started to close itself without any reason. To check if it was the extension, I had to delete it for a couple of days. After that, the problem was resolved. Please fix this problem because I love this extension.
  • (2021-10-13, v:1.0.1) Gary Ferland: still no images
    I am updated to 1.0.1 and have refreshed the browser. No background image, only white. The extension does do one thing - when enabled the hour numerical labels disappear but they come back when disabled. I also tried logging off and back on. Any suggestions? It was great while it lasted! thanks,

  • (2021-10-06, v:1.0.0) Makenna Swartz: Stopped Working
    Hi, starting off by saying I absolutely love this extension, and by now you are probably aware that it has stopped working. Many people were saying that it's probably the recent Chrome update that broke it, however that was about a week ago and it just stopped working today. Also, I uninstalled my chrome and reinstalled the version I had when I added the extension, and that still did not work. I saw on the chrome store that it said the extension was updated today, October 6th, so that update is the most likely cause of the recent problems. Just letting you know what I've noticed to maybe try and help you in your debugging process. Thanks again for creating such an amazing extension!
  • (2021-10-06, v:1.0.0) Adelie Plumasseau: It disappeared
