aSc TimeTables

aSc TimeTables is a dedicated scheduling solution designed to take the headache out of creating school calendars. Whether you manage a small primary school or a massive university, you can input your specific constraints—like teacher availability, classroom capacities, and subject requirements—to generate a balanced schedule automatically.

You can manage daily changes through the integrated substitution module, which tracks teacher absences and suggests the best available replacements in real-time.

It solves the perennial problem of manual scheduling by providing a digital environment that balances pedagogical needs with logistical reality.
