Add to Calendar button (for websites)

This tool provides a quick and effortless way for your users to add your events to their calendars. When you add an "Add to Calendar" button to your website, you increase the likelihood that your users will add your event to their calendars by reducing the time and effort required to do so. Easy to install, language independent, time zone and DST compatible. Works perfectly in all modern browsers, tablets and mobile devices.

Subscription Calendar (multiple events)

This tool allows your users to easily add multiple of your events to their personal calendars by subscribing to a calendar you create. But the coolest part? If you need to add or delete an event, or push the start time back half an hour because you forgot about your dog’s 2nd birthday party, you simply make the change on your calendar, and that change will be reflected on all of your subscribers’ calendars.

Event with RSVP (for newsletters and social sharing)

This tool makes it easy for your users to add your events to their calendars no matter where they learn about them - be it newsletters, social media like facebook or twitter, or campaign tools like MailChimp, Marketo, or Salesforce. Our event tool makes it quick and painless for you to create an event with its own landing page or an Event with RSVP which you can then share on social media, or use as a link in newsletters and campaign tools.

Direct URL Method (and API's)

Think of this as a supplemental tool that fills in any potential gaps left by the other tools. It is a customizable link that can be used to create an event on-the-fly, or send your users to their calendar service where they can add your event, or even attach your event to an email you send to your users. Essentially we’re doing our best to go overboard on the number of ways you can get your events in front of your users. Specifically on their calendars. Because that’s what we do.

This tool is an embeddable calendar, a subscription calendar, and a data collection service all rolled into one. As an embeddable calendar, it makes your events visually friendly for your users by giving them an actual calendar to look at on your website. As a subscription calendar, it allows your users to easily add your events to their calendars and stay up-to-date on any event changes (similar to the Subscription Calendar tool, though with more options and deeper analytics).

This tool provides usage stats and advanced data analytics for the Add to Calendar button tool, the Subscription Calendar tool, the Events tool, the Direct URL Method tool, and the CalendarX tool. (read: analytics for all the tools). This tool was built for you, to help you better understand your users and optimize your interaction with them. Because at the end of the day, it’s not about us or even you. It’s about them.
