Aprus Appointment Calendar

Aprus Appointment Calendar is a lightweight, no-frills booking plugin. You set your opening hours, drag-select the exact slots you want to be bookable, and clients book through a clean calendar embedded anywhere on your site.

Features

• Two client views — monthly calendar and weekly column layout
• Embed anywhere — [apruapca_calendar] shortcode, classic widget or Gutenberg block (Aprus Appointment Calendar / Aprus Appointment Calendar (columns))
• Admin availability grid — drag-select a rectangle over slots to open or close them in bulk. Booked slots are protected from accidental change.
• Appointment duration + break — control slot generation with duration and buffer between visits
• Working days & hours — per-day-of-week toggle, lead time (earliest booking), calendar range (how far ahead)
• Booking popover — hover a booked slot in admin to see client details and cancel with one click; cancellation sends an e-mail notification
• Automatic locale — Polish or English based on WordPress site language, English by default
• Respects your WP settings — start_of_week (Monday vs Sunday), time_format (24h / 12h AM-PM)
• E-mail notifications — customer + admin messages via wp_mail()
• No accounts required — clients book by e-mail

Free and open source

The plugin is fully free — no premium tier, no artificially blocked features. If you find it useful, you can buy me a coffee on Ko-fi or on buycoffee.to. It helps me keep the project maintained.

Privacy

The plugin stores appointment data (name, e-mail, phone, note, date, time) in your own WordPress database. Nothing is sent to third-party servers. E-mails go through the standard wp_mail() function.
