I made a similar template for myself using Excel, a bit fiddly, but it is specific to my location and from past experience. I separated each month into 4 weeks, and split each line in 2 (as sometimes you can still sow later crops, whilst the first lot have been planted out for successional harvesting). It looked something like the back of the colour codes you find on the back of some seed packets. More importantly, you can also learn when the harvest will be finished, so that you can plan the second crop for that area of ground, just by looking down the chart; eg. I plant out my leeks, usually after the overwintering broad beans have finished. Another good thing with the excel programme is that you can also use the grid like cells to plan the layout.
I hope the above makes sense, it's easier to see than to describe. It also makes the dark nights fly by, when I keep looking at my seed packets longing for spring :)
