Free tool, no sign-up
Find the double-bookings before the term starts.
Paste your weekly schedule. This checks every teacher, every batch and every room for overlaps, flags the impossible gaps, and shows you the week as a grid.

- Your timetable never leaves your device
Paste the schedule
Six columns: day, start time, end time, batch, teacher, room. The room can be left blank. A single cell like "9:00-10:30" in place of the two time columns works too.
Settings
Teacher load
Total scheduled teaching hours a week, per teacher.
Nothing is uploaded
The schedule is read by your own browser and checked on your device. Nothing is sent to us, there is no account, and nothing is stored after you close the tab.
Clashes
A clash is a real overlap. Back-to-back sessions, where one ends exactly as the next starts, are not counted.
Likely mistakes
Not clashes, but worth a second look before you print the timetable.
The week
Scroll sideways on a phone. Sessions involved in a clash are outlined.
What this does and does not check
It checks the rows you pasted for overlapping times. It does not know your holidays, your room capacities, or that two teachers share a name. If two people are both entered as "Sharma", they will look like one overloaded teacher.
