Image from store Google Calendar Event Checker
Description from store This extension is simple and does only one thing: marks an event's title in Google Calendar as completed (or canceled). There are few options to mark it: - s̶t̶r̶i̶k̶e̶t̶h̶r̶o̶u̶g̶h̶ effect - ✅ emoji in the beginning (to indicate event as completed) - ❌ emoji in the beginning (to indicate event as canceled) Everything is configurable in the extension Options. Also one warning for using strikethrough effect: make sure to use option "Add origin title to the description" in order to be able to find an event in search later. The nature of strikethrough effect changes event title. If you're having any issues and the extension doesn't work: - re-install the extension to make sure that you're using the latest version - enable error reporting in Options page - make sure that your ad blocking extensions (adblock, ghostery), if any, don't block "Sentry" (error reporting service) - try to use extension as usual: go to an event page and click the button, if it's there Doing these steps should generate and send error logs which could help me to debug the issue.

  • (2023-01-30) Steve Magruder: Works exactly as expected. Thank you for this extension! What would make this A+ perfect for me is if this also contained a setting to change the color coding of the event. E.g., I like to change my completed events/tasks to gray.
  • (2022-12-16) Steve Johns: It was working fine for the past two weeks. Today suddenly the check mark has disappeared. :( (Update: It's fixed now!)
  • (2022-10-28) Molly Hutt: This is a great idea, but I wish there were more aesthetic options, like a checkmark emoji without the bright green box. The box can be confusing or distracting if you already use emojis on your calendar, e.g., to indicate different types of events so you can tell them apart quickly. It's also not ideal if you're aiming to keep your calendar's color scheme subtle and calm. I may use it in the future, but it's not quite what I need right now.
  • (2022-09-29) Richard Kelley: This extension worked great for about a week. Now it no longer allows strikesthrough completed or cancelled events. The check mark and "x" shows up but is non-functional. Please fix !
  • (2022-09-07) Brooklyn Brackett: This extension had exactly the functionality I needed but unfortunately it only worked half the time. I open an event and there is no green check option for me to strikethrough the text. Please fix! This would be so helpful if it worked!
  • (2022-08-20) Oscar Viklund: I really like the strikethrough effect however it would be great if you could choose which emoji you wanted instead of the kinda ugly green one. But it works really well so I'm not complaining.
  • (2022-07-30) Intan: Exactly what is needed! Simple but functional! Thanks, dev!
  • (2022-05-10) Dan Fletcher: It really is absolutely fantastic & now is an essential feature on my calendar. If it was possible to check off events from Android as well it would be even better!! Many thanks to the developers.
  • (2022-02-25) Roddi Veet: Hi, is there an option to add more than one box, so it can look like the event was made or not like red and green color?
  • (2022-02-08) Luke Eros: Perfect.. Just what I needed
  • (2022-01-21) Forrest Elliott: Exactly what I was looking for! Now I can use google calendar to manage due dates without having to use tasks, which doesn't allow bulk csv import.
  • (2022-01-17) James Orestes: Very very cool. Exactly what I was looking for, For those of us using Brave, make sure Brave Shields is down for google calendar.
  • (2021-12-01) Mike D: Helpful! I don't understand why this isn't already a built-in feature from Google. I wish I could do this on Android App or by right clicking on the event.
  • (2021-06-29) David Haddad: AWESOME extension, I manage tasks and time in Google Calendar and this allows you to cross them out AND (optionally) add a check mark in front of the calendar item. Simple and perfect.
  • (2021-06-03) 跑跑: Nice!
  • (2021-02-12) Priyanka Upadhyay: Exactly what I was looking for. Made me ditch a to-do list app completely and now I use Google Calendar as the major to-do app. Thank you so much!
  • (2021-02-10) Molly Scott: Oh this is exactly what I was looking for! Thank you! So easy to setup and use. I am using it for a "School" calendar for my boys (homeschool) so they can mark the task as completed when they finish it.
  • (2020-09-22) Allie Pigg: Love this extension, but it randomly stopped working for me. The little green check mark box disappeared Google Calendar. 5 stars if you can get it fixed!
  • (2020-09-18) Carlos Armenteros M: super
  • (2019-01-25) Anastasia Nevolina: Love it! Make my checking routine more convenient and quick =) Saved a lot of time!

    was working until today
  • (2022-12-13, v:1.6.1) Hardline Exteriors: Check mark
    The box to click the check mark and strike through the title of an event is just gone. Help! This is crucial to our business. I've tried removing and adding the extension but its just gone.
  • (2022-10-21, v:1.6.1) Dawn Chadwick: Not working for every event
    I am using this to strikethrough appointments that have been canceled or rescheduled, but must remain on the calendar for records. My problem is that it isn't letting me consistently strikethrough every event. For example today, I had to cancel every appointment on the schedule. It let me strikethrough 4 out of 9 appointments. Is there a way to fix this? I already tried uninstalling it and reinstalling it.
  • (2022-10-14, v:1.6.0) Richard Kelley: Google Calendar Checker
    Running Mac Air Book M2. Extension completely stopped working Mac OS Montery 12.6 This is a great extension. Hope you can get it to work. I don't get either Check mark or the "X" mark. I have all the options checked.
  • (2022-05-10, v:1.4.0) Dan Fletcher: Now an essential feature of my calendar - is there any possibility of using it on Android as well?
    I now check off all of my calendar events in order to manage blocks of time effectively. At present, this only works when in front of my laptop, but it would be amazing if it were possible to check off events on the fly from Android as well. Is this something that is possible & what would it look like? Many thanks for your great extension!
  • (2022-05-08, v:1.4.0) Adrianna Flax: Disable Change of Event Email
    I like to add a checkmark to my event after it has happened, but I'd like to disable the automatic update email that all event attendees get when I add the checkmark. Is there a way to disable the updated event email?
  • (2022-03-08, v:1.4.0) Rodrigo Valenzuela Torrejon: One more Emoji
    Hi, I work with a team using google calendar side-by-side view to monitoring everyone events (zoom calls) this extension is great for that, I use ✅ when the the video call is on and ❌ when the person does not show up, could you add a neutral one, like when the event was interrupted or one of the participants left without notice. like a ⚠ yellow warning sign? would be great. thank you so much.
  • (2022-02-08, v:1.3.1) Luke Eros: add X Emoji to the title and X button to the edit field to mark as canceled
    Hi, Great addon, just what I needed. Is it possible for you to add X button to the edit field to mark events as cancelled and add the X Emoji to the title instead of check mark? thanks
  • (2021-09-19, v:1.1.0) Unwin Lodge: No checkmark visible
    I assume that if I have adblock or a pop up blocker or similar running I won't see the check box OSX Big Sur
