WebCalendar is a free, open-source, self-hosted calendar application for managing events, appointments and shared schedules. It suits small teams and organisations that want a simple shared calendar on their own server with user-level access control. It is best for calendar management rather than automated bookings, payments or sales scheduling.
What is WebCalendar?
WebCalendar is a PHP-based calendar application that runs on your own hosting account or server. You can use it as a personal diary, a shared team calendar, or a public events calendar that visitors can view without logging in.
It supports day, week, month and year views, recurring events, email reminders, calendar sharing and scheduling conflict checks. Users can also import and export events using common calendar formats, including iCalendar and .ics.
The official WebCalendar project page describes it as a flexible application for individual users, teams and public event listings. As of 2026, the project remains active, with recent development work focused on fixes, administration and installation improvements.
WebCalendar is free software released under the GNU General Public License version 2. You do not pay a per-user licence fee. However, you still need suitable hosting, a database and some responsibility for backups, updates and security.
Its technical requirements are relatively familiar for a web host:
| Requirement | What it means for a small business |
|---|---|
| PHP 8 or later | Your hosting account must support a current PHP version |
| Database | You can use options such as MySQL, MariaDB, SQLite or PostgreSQL |
| Browser access | Users manage calendars through a web browser |
| Cron access | Scheduled tasks may be needed for email reminders |
| Self-hosting | You control the application and its stored calendar data |
For non-technical site owners, the main question is not whether the software is free. It is whether your hosting provider makes installation and maintenance straightforward.
5 Best Features of WebCalendar
-
Multi-user calendars and access control
Create accounts for team members and control who can view or manage calendars. This is useful when an administrator, assistant or department needs to maintain another person’s schedule without giving every user full control. -
Flexible calendar views
Switch between day, week, month and year views depending on the task. A monthly view helps with planning, while a daily view is more useful for appointments, room bookings and detailed work schedules. -
Recurring events with exceptions
Set up repeating meetings, shifts or maintenance tasks without entering every occurrence manually. You can then override or delete individual instances when a particular date changes. -
Reminders, notifications and conflict checks
Email reminders can help users prepare for upcoming events. The conflict-checking feature also highlights overlapping commitments, which is valuable when several people share responsibility for the same schedule. -
Import, export and calendar publishing
Import events from iCalendar files and export calendars for use in compatible applications. You can also publish selected calendars, provide RSS access and subscribe to remote calendars, helping information move between systems.
These features give the application more depth than a simple list of appointments. They also make it suitable for organisations that need a central record of events while allowing different users to work with the information in their preferred way.
WebCalendar in Action: 3 Examples
1. A small team coordinating internal meetings
Example scenario: A five-person consultancy uses a shared calendar for client meetings, internal reviews and annual leave. Each person has an account, while an office administrator manages recurring team meetings and checks for clashes before confirming new appointments.
The calendar gives the team a single reference point without requiring every user to share personal login details. Individual permissions can also reduce the risk of someone editing an event they only need to view.
2. An organisation publishing public events
Example scenario: A community organisation maintains a public programme of workshops, talks and local activities. Visitors can view the calendar without an account, while authorised staff add or update events behind the scenes.
This approach can work well when the main requirement is a clear online timetable rather than a complete ticketing system. You may still need a separate registration or payment process if visitors must reserve and pay for places.
3. A distributed team working across time zones
Example scenario: A team in the UK and North America uses a shared calendar for project milestones, handovers and online meetings. Users check the calendar in a browser and subscribe to relevant feeds in compatible calendar software.
Time-zone settings and shared views can reduce confusion when people work in different locations. The administrator should agree a standard for event titles, time zones and ownership before the calendar becomes busy.
3 Things That Could Be Better
-
The interface feels more traditional than modern cloud calendars
WebCalendar concentrates on practical functionality rather than a highly polished, mobile-first experience. A small-business owner looking for an exceptionally simple interface may need time to learn where settings and administrative tools are located. -
It is not a complete appointment-booking platform
WebCalendar can manage appointments, but it is not designed around public booking links, payment collection, automated availability rules or customer relationship management. If your main goal is to let customers choose a time online, a dedicated scheduling service may be a better match. -
Self-hosting creates ongoing responsibilities
The software itself has no licence charge, but you remain responsible for hosting, backups, updates, user security and email configuration. A managed hosting provider can reduce this workload, but it cannot remove the need to review access permissions and keep your calendar properly maintained.
There is also no native CalDAV support listed in the project information as of 2026. That may matter if your team expects deep two-way synchronisation with every modern desktop and mobile calendar application.
Top 2 Alternatives to WebCalendar
- Nextcloud Calendar: A self-hosted option that sits within the wider Nextcloud platform. It is more suitable if you also want shared files, contacts and collaboration tools in the same environment.
- Google Calendar: A hosted service with a polished user experience, broad integrations and low technical overhead. It differs because Google manages the infrastructure, while WebCalendar gives you more direct control over the application and its data.
Choose WebCalendar when straightforward shared scheduling and self-hosting are priorities. Choose an alternative when you need broader collaboration features, consumer-style usability or advanced booking workflows.
3 Tips to Get More From WebCalendar
-
Create a permission plan before adding users
Decide who can create, edit, delete and publish events. Use the least permissive access level that still lets each person complete their role. Review administrator accounts regularly and remove access when someone leaves. -
Standardise event naming and information
Agree a format such as “Client : meeting type : owner”. Add useful details to the description, including the location, meeting link, preparation notes and responsible person. Consistent entries make a shared calendar much easier to scan. -
Test reminders, backups and publishing settings
Add a test event and confirm that reminders are delivered correctly. Check that your backup process includes the application database and uploaded files. If you publish a calendar publicly, review it from an unauthenticated browser to make sure visitors see only the information intended for them.
For a broader online presence, you can also combine a calendar with a professionally managed website. Zest City can help with website design services when your calendar needs to sit within a clearer, more effective customer journey.

FAQs
Is WebCalendar free?
Yes. WebCalendar is free, open-source software, so there is no per-user licence fee for the application. You still need to pay for suitable hosting if you do not already have a server, and you should account for maintenance and backup work.
Can WebCalendar share calendars with a team?
Yes. It supports multiple users, shared calendar views and user-level access management. Administrators can decide who can view or manage particular schedules, which makes it suitable for small teams and organisations.
Is WebCalendar good for booking appointments?
WebCalendar is useful for recording and coordinating appointments, but it is not a specialist customer booking system. It does not focus on features such as public booking links, online payments, automated availability routing or CRM workflows.
Is WebCalendar still maintained?
As of 2026, the project shows ongoing maintenance activity, including recent fixes to the login page, event administration and installation-related functions. Open-source project activity can change over time, so review the current release and support information before using it for a critical system.
