Day-Wise Timetable Maker: When Every Day Has a Different Schedule

A teacher wrote to us last month with a short question.

"Can you add day selection to the timetable?"

We asked what she meant. Her answer was one line: "We use day-wise timetable."

That one line describes a completely different piece of software.

There Are Only Two Kinds of School Timetable

In every school in the world, the timetable is one of two shapes.

The first repeats. Period 3 is Maths for Class 8A on Monday, and it is also Maths on Tuesday, Wednesday, Thursday. You build one week — really, you build one day — and it runs unchanged until the term ends. This is the norm across most of Pakistan.

The second changes daily. Class 8A has Maths then English on Monday, English then Science on Tuesday, and something else again on Wednesday. Each day is its own timetable. This is the norm across most of India, the UK, and much of the rest of the world.

Schools almost never switch between the two. If your school is day-wise, it has always been day-wise, and the idea of a repeating timetable seems strange. If your school repeats, the day-wise version looks like needless work.

Here's the part that matters: these are not the same problem with a setting toggled. They are different problems.

Why Day-Wise Is So Much Harder

Take a small school. Fourteen classes, eight periods.

A repeating timetable is 14 × 8 = 112 decisions.

A day-wise timetable across Monday to Friday is 14 × 8 × 5 = 560 decisions.

Five times the work is bad enough. But the real difficulty isn't the volume — it's that the clashes multiply too.

In a repeating timetable, "Sir Usman is in Period 3" is a single fact. Check it once, and it holds all week.

In a day-wise timetable, Sir Usman being in Period 3 on Monday tells you nothing about Period 3 on Tuesday. Every day has to be checked independently. A teacher can be double-booked on Wednesday while Monday and Tuesday are perfectly fine.

This is why so many schools running day-wise timetables end up keeping a second document — a hand-written list of who clashes where. The spreadsheet holds the timetable; a separate page holds the conflicts. And the moment anyone edits the timetable, the two drift apart.

What Breaks in a Normal Spreadsheet

Ask anyone maintaining a day-wise timetable in Excel and you'll hear the same three complaints.

One: the clash list is always slightly wrong. It was accurate when it was written. Then someone swapped two periods on Thursday and forgot to update it.

Two: nobody can see a single teacher's week. The spreadsheet is organised by class, because that's how you build it. But teachers keep asking "what's my Wednesday?" — and answering means reading across five separate sheets, one cell at a time.

Three: it's five times the typing for a week that's mostly the same. Most schools repeat 60–80% of a day. Tuesday is Monday with three changes. But a blank spreadsheet doesn't know that, so you type all of it out again.

What a Day-Wise Tool Should Actually Do

When we built ours, those three complaints set the requirements.

Copy a day, then edit the differences. Build Monday properly. Copy it across the whole week in one click. Then change only the periods that actually differ. That turns 560 decisions back into something closer to 150.

Detect clashes per day, not per period. A teacher in Period 1 on Monday and Period 1 on Tuesday is not a clash — and a tool that flags it is worse than useless. Only a genuine same-day, same-period conflict should turn red. Ours also warns you in the dropdown before you assign someone, showing which class they're already in.

Generate the teacher view instead of maintaining it. If the timetable already knows who teaches what and when, nobody should be keeping a second list. Switch to the teacher view and every teacher's full week is there, built from the grid itself. Double-bookings appear as two classes stacked in one red cell — the clash list writes itself.

Handle teachers who aren't in every day. Visiting and part-time staff are common, and scheduling them on a day they don't come in is an easy mistake to make. Mark which days each teacher is actually available and the tool stops offering them on the others.

Printing Is Its Own Problem

A day-wise timetable has three dimensions — class, day, period — and paper has two. You cannot print it as one table.

So there are three sensible layouts, and a school needs all of them at different moments:

• One page per day — the master sheet for the staffroom wall
• One block per class — the sheet that gets pinned up in each classroom
• One block per teacher — the slip you hand to each member of staff

We generate all three, as PDF or Excel. When two teachers land on the same printed page, there's a dashed line between them so you can cut it cleanly.

Which One Do You Need?

If Period 3 is the same subject every day of the week, you want the repeating timetable maker. It's simpler, faster, and asks you for far less.

If Monday and Tuesday look different, you want the day-wise timetable maker.

Both are free, both work in your browser, and neither asks you to make an account. Your timetable is saved on your own device — nothing is uploaded anywhere.
