Built with Python, SQLite, and python-telegram-bot, this template is not just a simple script — it's a complete CRM system inside Telegram.

🔥 KEY FEATURES:
- 📅 Smart Booking System: Clients choose a service, date, and available time slot. The bot automatically prevents double-booking.
- 🛡 Admin Panel: You can add/remove specialists, add services (with prices and durations), and view all upcoming appointments.
- ⏰ Automated Reminders: The bot automatically sends reminders to clients 24 hours and 2 hours before their appointment.
- 🌍 Multi-Language Support: Fully translated in Russian and English. Clients can switch languages instantly.
- 🌐 Time Zone Support: Built-in IANA time zone management (no more UTC conversion errors!).
- 💾 SQLite Database: All data (clients, services, schedules) is saved locally in a structured database.

📦 WHAT YOU GET:
- Full, well-structured Python source code (multiple modules for clean architecture).
- Database initialization script (creates all tables automatically).
- Detailed step-by-step README (How to set up and run).
- Requirements file for quick installation.

💡 PERFECT FOR: Developers looking to sell a ready-made bot to local businesses, or salon owners who want to automate their booking process.

⚠️ REQUIREMENTS: 
You need basic knowledge of running Python scripts. The bot requires a Telegram Bot Token (from BotFather) and your numeric Telegram ID. Python 3.10+ is recommended.
