Sometimes calendar days are a bit messy. I have lots of squiggles, lines and small annotations. Every night I sit down and plan the following day. If the day is a bit of a mess, I rewrite the times at the bottoms of the days, as you can see for Monday 12th and Wednesday 14th. This is so I have a quick overview of my day. If the day is extremely messy, right into the evening, I put a large sticky note over the day and rewrite it.
I ordered some stationery a few weeks ago. Nothing urgent, but it was delayed to to the pandemic. As a token of apology I received some candy, a pen and these lovely sticky notes. I had used them before but battled to find them again.
These sticky notes are in the chronodex/spiraldex format, so you can look at the sticky notes as a clock and write notes in the small grids.
Of course you could do it in more detail and more neatly than I did, but it works perfectly if you have learned to tell time on a clock. Our minds tend to be used to both diary format and clock format, so it is a small leap to get used to, if you picture time in this way. I only work from 7 to 18.15 but you could use the different levels of the clock to make it a 24 hour clock as in Patrick Ng’s Chronodex below.
