Sniza Appointment Scheduler for WordPress

Sniza Appointment Scheduler is a self-hosted booking system for sites that sell instructor time in prepaid blocks. Students draw down minutes from packages assigned by an admin or purchased through WooCommerce, and book appointments against per-instructor availability.

Features:

Per-instructor weekly availability (timeblocks) and ad-hoc time off

Configurable package definitions in 30 minute increments up to 4 hours

Admin-assigned prepaid packages with optional expiration date and notes

Optional WooCommerce integration: mark packages as purchasable and auto-grant minutes when an order completes

Frontend month calendar with day-level availability indicators

Weekly time-slot view with status colours (available, booked, time off, blocked by another user, too soon, current)

Mobile single-day scheduler with mini calendar

Per-user appointment booking and cancellation, with a configurable cancellation cutoff

“My Lessons” view with AJAX-powered Future / Past filter and in-place cancellation

Admin Appointments screen with instructor and date-range filters (defaults to the next 3 days, hides cancelled lessons)

Configurable maximum appointment length (admin setting)

Sample-data tool for seeding and wiping a fixed demo dataset

Timezone-aware: each instructor has their own timezone, and end users see times in the site timezone
