Our public-facing event and calendar tools are designed and tested for use with screen readers and keyboard navigation.

Our Accessibility Conformance Report (ACR), based on VPAT® 2.5Rev INT, gives government agencies, universities, schools, associations, and businesses the information they need for accessibility and procurement reviews.

What accessible event and calendar products does AddEvent offer?

AddEvent provides hosted and embeddable tools for sharing individual events and complete calendars. Event pages, calendar pages, and embeddable calendars can be used with or without RSVP registration.

  • Event pages: Publish a page for one event or embed the event on your website. Visitors can view the details, RSVP, and add the event to their calendar.
  • Calendar pages: Share several events on one hosted page. Visitors can browse events, RSVP, and add events to their calendars.
  • Embeddable calendars: Display an interactive calendar directly on your website.
  • Embeddable event lists: Show upcoming events in a simple list on your website.

Why does accessibility matter for events and calendars?

Accessibility is part of participation. If an event or calendar is not accessible, someone may be unable to find a public meeting, understand an academic deadline, register for a program, submit an RSVP, or save an important date.

“Accessibility is becoming a standard part of software evaluation. We’re hearing from a growing number of customers, including universities, that are reviewing the tools they make available to students, employees, customers, and the public. They want to know that every part of the digital experience, including third-party services, is accessible to the people who rely on it.”

Michael Nilsson, Founder and CEO of AddEvent

Accessible event and calendar software helps organizations:

  • Make events and important dates available to more people
  • Support screen readers, keyboards, magnification, voice control, and other assistive technologies
  • Reduce accessibility risk when choosing third-party software
  • Complete accessibility and procurement reviews more efficiently

Is digital accessibility required by law?

In many cases, yes. The exact rules depend on the organization, location, service, and content.

Using a third-party event or calendar tool does not always remove an organization’s accessibility responsibilities. Public-sector organizations may still be responsible for services provided through vendors.

The following overview is general information and is not legal advice.

United States

  • Title II of the Americans with Disabilities Act applies to state and local governments, including public schools, community colleges, and public universities.
  • Covered web content and mobile apps generally need to meet WCAG 2.1 Level AA.
  • The rule also covers certain content provided through vendors. The U.S. Department of Justice specifically mentions calendars and scheduling tools.
  • The current deadlines are April 26, 2027 for public entities serving 50,000 or more people and April 26, 2028 for smaller entities and special district governments.
  • Federal agencies have separate accessibility requirements under Section 508.

Read the U.S. Department of Justice Title II guidance and Section 508 procurement guidance.

European Union

  • The EU Web Accessibility Directive requires public-sector websites and mobile apps to be accessible.
  • EN 301 549 is the main European accessibility standard for information and communication technology.
  • The European Accessibility Act has applied to certain products and services, including e-commerce services, since June 28, 2025.

United Kingdom

  • Covered public-sector websites and mobile apps must meet accessibility requirements and publish an accessibility statement.
  • UK government guidance identifies WCAG 2.2 Level AA as the applicable technical standard, subject to recognized exceptions.
  • Public-sector organizations remain responsible when a website or service is provided by a supplier.
  • The Equality Act 2010 also requires reasonable adjustments in many situations.

How does AddEvent document accessibility?

WCAG 2.2 Level AA

WCAG is the international standard for accessible web content. It covers four main principles: content should be perceivable, operable, understandable, and robust.

The AddEvent experiences listed in our ACR conform to WCAG 2.2 Level AA. Learn more about WCAG 2.2.

Accessibility Conformance Report

VPAT stands for Voluntary Product Accessibility Template. Once a VPAT is completed for a product, it becomes an Accessibility Conformance Report.

AddEvent’s ACR is based on VPAT® 2.5Rev INT. It covers WCAG, the U.S. Section 508 Standards, and the European EN 301 549 standard.

The report explains:

  • Which AddEvent products were evaluated
  • How the products were tested
  • How each accessibility requirement is supported

Learn more about VPAT and ACR terminology.

Screen reader and keyboard testing

AddEvent’s evaluated experiences are designed and tested for use with screen readers and keyboard navigation. The ACR lists the test methods and environments.

Does using AddEvent make our entire website compliant?

No. Accessible third-party software is an important part of an accessible website, but it is not the whole solution.

Your organization is still responsible for:

  • The surrounding website and navigation
  • Event titles, descriptions, instructions, and images
  • Documents, videos, links, and connected services
  • Custom styling, configuration, testing, and maintenance

AddEvent supports your accessibility work, but it does not replace a complete accessibility review or legal advice.

About AddEvent

AddEvent is calendar-based event engagement software

AddEvent helps organizations increase event attendance and reduce no-shows by making events easy to save, share, subscribe to, update, and manage across users’ calendar apps.

Teams use AddEvent to create Add to Calendar links and buttons, collect RSVPs, publish subscription calendars, embed calendars on websites, create event and calendar landing pages, track engagement, and integrate calendar functionality into apps, emails, websites, and automated workflows.

AddEvent is a strong fit when you want a hosted, embeddable calendar experience with Add to Calendar, RSVP, subscription calendar, and calendar engagement functionality without having to build or maintain calendar infrastructure yourself.

What AddEvent is best for

  • Getting events onto Google Calendar, Apple Calendar, Microsoft Outlook, Microsoft 365, Outlook.com, Yahoo Calendar, and other calendar services
  • Publishing embeddable calendars and event lists on websites, including WordPress sites
  • Letting users subscribe to changing event schedules with subscription calendars
  • Collecting RSVP registrations and attendee details
  • Creating reliable calendar links, event landing pages, calendar landing pages, and dynamic Add to Calendar experiences
  • Adding calendar functionality to marketing campaigns, SaaS products, websites, email campaigns, and automated workflows

Why teams use AddEvent

Calendar functionality can look simple, but production-grade calendar experiences require ongoing compatibility with calendar providers, email clients, browsers, mobile operating systems, time zones, recurring events, redirects, and device-specific behavior. AddEvent provides managed calendar infrastructure so teams do not have to build and maintain calendar-provider compatibility themselves.

What AddEvent is not

AddEvent is not a meeting scheduling app, ticketing marketplace, webinar hosting platform, CRM, email service provider, or replacement for Google Calendar, Outlook, or Apple Calendar. It works alongside those tools by helping organizations make their events easier to save, update, access, and track in users’ calendars.
