Everything runs on your own WordPress: no external fonts, no CDN, no tracking, no account. Dates can come straight from your posts. Set a date while you write, for example the cinema release of a film, a book release or a match day, and the post appears in the calendar by itself, with its title, link and image. A date you already keep in a custom field (Advanced Custom Fields, Meta Box or any other plugin) can be used without entering anything twice. Visitors can add a single event to their own calendar or subscribe to the whole calendar (or one category) on their phone. Changes appear there automatically. #### Key Features * **Unlimited Events**: Create as many events as you need * **Dates from Posts**: A date field in the post editor (block editor and classic editor) for posts, pages and custom post types; the calendar entry stays in sync with title, link, image and date * **Existing Date Fields**: Use a date you already store in a custom field (ACF, Meta Box, any plugin) and apply it to all existing posts with one click * **Date Box in Posts**: Block “Date of this post” or `[threecal_post_date]` shows the date with an “Add to my calendar” button, also automatically at the start or end of a post * **Poster View**: Upcoming dates as large tiles with the post image, for example“ This week at the cinema” * **Postponed Dates**: When a published date moves, the calendar shows “Postponed, previously …” and subscribers get the new date * **Only the Month Known**: For festivals and other dates of which only the month is set, the calendar shows “July 2027, date to be announced”; the month view lists them in a bar above the grid. Such dates stay out of the iCal feed and the event schema until the day is known * **CSV Import**: Import events from a spreadsheet. A preview shows what happens before anything is saved, and importing the same file again updates the events instead of creating duplicates. Also available as WP-CLI command `wp threecal import` * **Recurring Events**: Daily, weekly, every two weeks, monthly or yearly, with an end date; single dates can be cancelled, removed or changed on their own * **Cancelled Events**: A cancelled date stays visible, crossed out, so nobody turns up in vain; subscribers and search engines get the cancellation too * **iCal Export and Subscription**: “Add to my calendar” for every event and a subscription feed (all events or one category) for Google Calendar, Apple Calendar, Outlook and Thunderbird * **German Translation**: Informal (du) and formal (Sie) German included * **Unlimited Categories**: Organize events with color-coded categories * **Month and List Views**: Multi-day events appear on every day they cover * **Three Designs**: Clear (light), Accent (bold color header) and Night (dark), with your own accent color; events take their category color automatically * **Responsive**: Adapts to small screens * **Gutenberg Block**: Live preview in the editor, choose view, design and category * **Shortcodes**: Flexible placement options * **Schema.org SEO**: Event markup with ISO dates and time zone for events at a real place; office hours, holidays or release dates can be excluded per category, as Google requires * **Route Link**: “Plan route” opens OpenStreetMap only when the visitor clicks it * **Accessible Popup**: Dialog role, keyboard focus and Escape to close * **Mobile List**: On small screens the calendar starts in list view * **GDPR Friendly**: Made in Germany with privacy in mind #### Easy to Use 1. Install and activate 2. Create your first event 3. Add the calendar to any page with shortcode or Gutenberg block 4. Done! #### Shortcodes **Display Calendar:** [threecal] Options: `view` (month, list), `category`, `location`, `theme`, `show_filters`, ` show_legend`, `show_subscribe`, `mobile_list` (true/false). **With Options:** [threecal view=”month” category=”1″] **Event List:** [threecal_events limit=”10″] Options: `view` (list, grid, compact, poster), `category`, `location`, `limit` ( per page), `columns`, `show_past`, `show_pagination`, `month` (current, next or a month such as 2026-10), `running` (number of days). **A Whole Month, for Example “Releases in October”:** [threecal_events view=”poster” month=”2026-10″ category=”1″] **Now Showing (Started Within the Last 40 Days):** [threecal_events view=”poster” running=”40″ category=”1″] **Posters with Post Images:** [threecal_events view=”poster” category=”1″ columns =”4″] **Date of a Post (with “Add to my calendar”):** [threecal_post_date] **Upcoming Events:** [threecal_upcoming limit=”5″] **Mini Calendar (Perfect for Sidebars):** [threecal_mini] #### Gutenberg Block Simply search for “3task Calendar” in the block inserter to add a calendar to any page or post. #### No feature locks 3task Calendar works completely on its own. Every feature in this plugin is unlocked. ### External Services 3task Calendar does not connect to any external service. The “Plan route” link of an event opens OpenStreetMap in a new tab only when a visitor clicks it; nothing is sent before that. ### Credits Icons: [Tabler Icons](https://tabler.io/icons), MIT license, embedded as inline SVG (no icon font, no external request). ### About 3task.de 3task Calendar is developed by **3task.de**, specialists in WordPress plugin development.

Upload the plugin files to `/wp-content/plugins/3task-calendar/` 2. Activate the plugin through the ‘Plugins’ menu in WordPress 3. Go to 3task Calendar in your admin menu to create events 4. Add the calendar to any page using `[threecal]` shortcode or Gutenberg block ## FAQ ### How do I display the calendar? Use the shortcode `[threecal]` or add the 3task Calendar block from the Gutenberg editor. ### Can I have multiple calendars? Yes! Each shortcode or block is an independent calendar. You can filter by category. ### How do I style the calendar? The calendar automatically adapts to your theme. You can also add custom CSS for further customization. ### Is this plugin GDPR compliant? Yes. 3task Calendar is developed in Germany with privacy in mind and makes no external requests: no web fonts, no CDN, no tracking, no account. Visitor data stays on your site. ### Does the plugin send data to external services? No. The calendar, the iCal files and the subscription feed are generated by your own site. The “Plan route” link only opens OpenStreetMap when a visitor clicks it. ### Can I put posts into the calendar? Yes. Under 3task Calendar > Posts, switch on the date for posts, pages or a custom post type and give the field a name, for example “Release date”. While writing, set the date in the editor sidebar. The post appears in the calendar once it is published and disappears again as a draft or in the trash. ### I already store dates in a custom field. Do I have to enter them again? No. Choose the field under “Date comes from”. The list shows every field that holds dates, how many posts use it and an example value, so the right one is easy to spot.“ Apply to existing posts” puts all of them into the calendar in one go. Dates like 2026-10-01, 20261001 (ACF), 01.10.2026 and Unix timestamps are read, and changes made by imports or other plugins are picked up automatically. ### What if only the month of an event is known? Choose “Only the month is known” when editing the event and pick the month. Visitors see “July 2027” with the note “Date to be announced”. In the month view the event appears in a bar above the grid instead of on the 1st. It is left out of the iCal feed and gets no event schema, because Google requires a concrete date. Once the day is known, switch back to “The date is known”; this is not shown as “Postponed”. The same option exists for dates from posts with their own date field. ### How do I import events from a CSV file? Go to 3task Calendar > Import, upload the file and check the preview. Nothing is saved before you click “Run import”. The file is UTF-8 (with or without byte order mark), the separator ; or , is found automatically, at most 2 MB. A sample file can be downloaded on the same page. Columns (first line, upper or lower case does not matter): * `import_key`: your own unique key; a row with an existing key updates that event, so a second import creates no duplicates * `title` (required) * `start` (required): `2027-07-10`, `2027-07-10 20:00` or `2027-07` when only the month is known * `end`: `2027-07-12` or `2027-07-12 23:00` * `all_day`: 1 or 0 * `url`, `description` * `category`: name, several separated by `|`; missing categories are created * `location_name`, `address`, `postal_code`, `city`, `country` (two letters, e. g. DE): a location with the same name and city is used again * `status`: draft, publish or cancelled; overrides the status chosen on the import page When an event is updated, it keeps its status and the columns that are not in the file. On the command line: `wp threecal import events.csv --dry-run` checks the file, `wp threecal import events.csv --status=publish` imports it. ### Why do some events not appear in the event schema? Google only accepts events that take place at a real location on a concrete date, and it does not allow office hours or release dates as events. Events without a location or with only the month known get no markup, and every category can be excluded with “Not an event for search engines”. ### How do visitors subscribe to the calendar? Every calendar shows a “Subscribe to this calendar” link. It opens the calendar app via webcal://. The address can also be copied into Google Calendar (“From URL”). Use `[threecal category="2"]` to offer a feed for one category only. ### How do recurring events work? Choose a repeat pattern and an end date when editing an event. The plugin creates the single dates. Below the form, “Dates of this series” lists every date: cancel one (it stays visible, crossed out), restore it, remove it or edit it on its own. ### Does the calendar work with page caching plugins? Yes. Month navigation and the event popup use public read-only requests without a nonce, so cached pages keep working. ### Where can I get support?
