Keep track with changes made on AddEvent.
It's sort of a change log and an information board to keep you in the loop.

Update (Friday, April 8, 2016)


We updated the documentation on event listeners used in the "Add to Calendar" + "Subscribe to Calendar" sections to include the new "window.addeventasync" method.

Update (Thursday, March 31, 2016)


One of our users asked us to take a look at the buttons when used on mobile devices. The user had a lot of users who are elderly and they press (tab) the screen by holding down their finger for a long time (instead of a quick tab). This behavior would result in the drop down collapsing because we would expect the touch event to be executed. We have changed our scripts to adapt to this behavior and our users elderly audience can now use our buttons properly too.

These buttons have been updated:
"Add to Calendar" version 1.6.1 and "Subscribe to Calendar" version 1.0.2.

Update (Thursday, March 24, 2016)


Microsoft is currently in the process of upgrading all of their accounts into the new Outlook.com. Unfortunately it has resulted in the way we used to add an event to the Outlook.com calendars has changed. At least for now and until Microsoft changes / fixes their code. We have reached out to the Outlook.com team, but fixing issues can take a while.

Our job is to provide our users with a service that works. Therefore we have changed our approach to fit the new Outlook.com and we are glad to inform you that adding an event to Outlook.com now works again. We will continue to check if Microsoft fixes the issue and roll out new updates if they do.

Update (Tuesday, March 22, 2016)


We have noticed that the good people at Microsoft are upgrading more and more old Hotmail.com users into the new Outlook Calendar Live environment. Our own accounts were recently upgraded / moved. Since the upgrade / move adding an external event to the calendar often fails. Users are met with a "Calendar isn't available" notice. It seems that it work for some and fail for others. We have notified and reached out to the Outlook / Live team and will continue to do so until the new platform is stable / the issue has been resolved.

Update (Sunday, March 20, 2016)


When a user clicks the Outlook or Apple options in the "Add to Calendar" button, a calendar file is generated and downloaded to the users computer. We often get asked if it's possible to custom name that file and now it is.

In order to use custom file naming you must add a new parameter "calname" in the button code.


<div title="Add to Calendar" class="addeventatc">
    Add to Calendar
    <span class="calname">Custom event filename</span>

If calname is not specified the name defaults to "event.ics" as we are used to. You can use the phrase "use-title" to use the title from the "title" parameter or enter a custom file name.

Update (Friday, March 4, 2016)


We are currently experiencing some issues with our platform (the service is slow but works). We are investigating what the cause is and will fix it asap.


Due to a massive amount of incoming data (usage and statistics) our databases have been slow the past couple of hours. We have increased the levels and disabled statistics temporary to ensure that all traffic gets through.

Update (Friday, February 26, 2016)


We added Bower support for the "Add to Calendar" button. Developers using Bower can install the button script using this command:

bower install AddEvent

Update (Monday, February 22, 2016)


A lot of our users use the "One-time Events" to create events for sharing and embedding into newsletters. We have had several users asking us if they could create the events on their own website or intranet instead of having to sign into AddEvent.com every time.

We have created a popup / modal window which easily can be added into any website / intranet. The popup contains a list of events grouped by months and allows you to create / edit / delete your events as you know it from the "Events Manager".

We call the modal a widget and you can find it in the new widgets section.

Update (Monday, February 8, 2016)


We recently added asynchronous handling of the "Add to Calendar" and "Subscribe to Calendar" scripts. In order to use the additional settings script with an asynchronous loaded script you have to wrap the script into our new "ready" event listener. It looks like this:

window.addeventasync = function(){

Update (Friday, January 29, 2016)


A few of our users have reported that the "Add to Calendar" and "Subscribe to Calendar" buttons sometimes don't load correctly in the most recent Microsoft browsers. When not loaded correctly, the buttons will seem to be unstyled and the drop down functionality doesn't work.

When using external scripts on your website (which many do with AddEvent), the browser can miss out on necessary function calls. In order to help out the browser, loading external scripts asynchronous in the best way to do it. We have added some modern tags (async defer) to our script sources and updated the "Add to Calendar" and "Subscribe to Calendar" sections.

Below is an example on how to load AddEvent asynchronous:

<script type="text/javascript" src="https://addevent.com/libs/atc/1.6.1/atc.min.js" async defer></script>
