What is Webcalendar?
WebCalendar is a free, open-source calendar application written in PHP, originally released in 2001 and licensed under the GPL. It is designed for shared scheduling: multiple users, multiple calendars, group events, repeating bookings, and email reminders, all driven from a web interface that does not depend on any external service.
The application supports per-user permissions, public read-only calendars, NIS or LDAP authentication for organisations that want it, and iCalendar import and export. The frontend is plain HTML with light JavaScript, so it works on minimal browsers and older devices. Database support covers MySQL, MariaDB, PostgreSQL, Oracle, and SQLite.
Development pace has slowed considerably from its peak in the mid-2000s, but the project still ships occasional point releases and the codebase is small enough to audit and patch in-house when needed. WebCalendar runs on a standard PHP and MySQL or MariaDB stack, with no JavaScript build step or framework dependency.
365i’s editorial review of Webcalendar
WebCalendar is one of the older PHP applications still in regular use on our platform, and I am not going to pretend otherwise. The vendor description above is accurate. What it does not say is that the project is essentially in slow maintenance now, the interface looks like 2005, and for most teams asking us about shared calendars in 2026 the right answer is Google Workspace or, for the self-hosted crowd, Nextcloud Calendar.
That said, WebCalendar still has a niche, and the people in that niche have very good reasons to be there. I see it most often on three kinds of accounts: small public-sector teams who need a calendar that lives on a UK server they control, schools and clubs running shared room or pitch booking schedules, and long-time users who set it up fifteen or twenty years ago and have built routines around it that are not worth breaking.
"For most teams in 2026, WebCalendar is the wrong answer to the shared calendar question. For the small minority who genuinely need self-hosted, no-cloud, no-tracking, audit-friendly scheduling, it is still one of the cleanest options on the table."
Mark McNeece, Founder, 365i Hosting
What works well: the application is tiny by modern standards, which means it is fast, easy to back up, and easy to inspect. The permissions model is genuinely flexible. Public read-only calendars work well for community organisations who want to publish a fixtures list or a meeting schedule without exposing booking controls. iCalendar import and export means you can get data in and out without screen scraping. And because the codebase is small and stable, we have clients running installs that have not needed touching for years.
What is annoying: the interface is dated and looks worse on mobile than on desktop. There is no native push notification, just email reminders. Recurring event handling has rough edges around exceptions and exclusions, particularly across daylight saving transitions. The plugin scene is essentially nonexistent, so anything you want that is not in the box, you build yourself or do without.
Hosting notes: WebCalendar is one of the cheapest applications to host that we offer. It barely uses any memory, the database stays small unless you have hundreds of users, and the disk footprint is negligible. PHP 8.1 works with a small number of deprecation notices that we can suppress at the server level. Our standard web hosting plan is more than enough. Daily backups via the control panel cover both files and database, which is all the disaster planning a calendar install needs.
If you have an existing WebCalendar install that works for you, keep it. We will host it cheerfully and quietly. If you are choosing a calendar tool today with no history, please look at Nextcloud Calendar on a small managed cloud server, or just use Google Workspace and stop self-hosting calendars unless you have a specific reason.

Where Webcalendar Fits
Best for
Small UK clubs, schools, parishes, and public-sector teams who need a self-hosted shared calendar on a server they control, particularly for room or pitch booking and published fixtures lists. Also suits long-running installs where the workflow is bedded in and a platform migration would cost more than it would save. Runs comfortably on our standard web hosting plan with PHP 8.1 and MySQL.
Watch for
The interface is dated and the mobile experience is poor. Recurring event handling has rough edges around exceptions and daylight saving transitions, so test repeat patterns carefully before relying on them. There are no native push notifications, only email reminders. New teams in 2026 with no prior WebCalendar history should evaluate Nextcloud Calendar or Google Workspace before committing to self-hosted PHP scheduling.

A Webcalendar case from our books
A west midlands sports club running pitch bookings for around forty teams across two grounds came to us in 2025 after their previous host warned them that PHP 5.6 was being retired. Their WebCalendar install had been live since 2008 and the bookings secretary did not want to learn a new system at the same time as moving hosts.
We migrated the install onto our standard web hosting plan, brought it forward to PHP 8.1, suppressed a handful of deprecation notices that were filling the error log, and tightened up the database with a few missing indexes that had never been added in twenty years. The bookings secretary noticed that the monthly view, which had taken around six seconds to load on the old host, now rendered in well under one. Total migration took half a working day. Annual hosting cost dropped by roughly £140 because we did not need to push them onto a paid VPS plan.
What we would tell anyone in the same spot: do not change platforms because of a forced PHP upgrade. The application is fine. Move hosts, fix the PHP version, and revisit platform choice on your own schedule.

What we look for in online calendar software hosting
Self-hosted calendars are tiny applications by modern standards. The interesting questions are reliability and timezone handling, not raw performance. We make sure the server timezone is set correctly during install, tune cron for repeating-event handling, and recommend a managed cloud server only when you cross several hundred concurrent users. Public read-only feeds work well behind the CDN, which we configure on request.

Webcalendar Hosting FAQ
Common questions we hear from people running Webcalendar on our hosting.
WebCalendar runs on PHP with MySQL, MariaDB, PostgreSQL, Oracle, or SQLite. The current release supports PHP 7.x officially. We run it on PHP 8.1 with a small number of deprecation notices suppressed at the server level. The application is tiny and uses very little memory, so any of our web hosting plans will run it without tuning.
WebCalendar is a one-click install from the My365i control panel. Open Software Installer, search for WebCalendar, pick the domain, and click Install. The installer creates the database, copies the files, and runs the initial setup. The whole process takes under two minutes. From there you log into the admin user and configure your calendar groups and permissions.
It is, but slowly. Releases come out occasionally rather than on a regular cycle, and the project is essentially in long-term maintenance rather than active feature development. The codebase is small enough to audit and patch in-house if needed. For an existing install with a working setup that is usually fine. For a brand new project in 2026, evaluate Nextcloud Calendar or a modern SaaS calendar first.
Our support covers the hosting platform: PHP, MySQL, SSL, backups, and migrations. We have helped enough WebCalendar installs that we are usually familiar with the common issues, particularly around PHP version upgrades. We do not write custom WebCalendar code or design your booking workflow, but we will tell you honestly when an issue is hosting-side and we should fix it, or application-side and you need a developer.
Yes, and we will do the migration for you free of charge on any of our hosting plans. We move the application files, the database, and any local configuration. We will also bring the install forward to a current PHP version and tidy up any error log noise that has accumulated over the years. Most WebCalendar migrations finish inside half a working day with no visible downtime to your users.
For most teams, yes. If you are already inside Google Workspace or Microsoft 365, just use the calendar that is already in your subscription. If you specifically want self-hosted, Nextcloud Hub includes a modern calendar with mobile apps, push notifications, and proper recurring event handling. WebCalendar still earns its place where the workflow is established, the data needs to live on a UK server, and the simplicity of the codebase is a feature rather than a bug.
