I don't like that week numbers are (documented as) mandatory. I wouldn't see myself grepping on a week number. I'd end up constantly looking up the correct week number in order to annotate each event properly, with no benefit in return. Then again, could write a macro/plugin thingy for one's editor of choice, to fill in the week number for you (ditto for day of week, which I would at least find quite useful, but which would similarly be a right pain to have to fill in manually all the time).

Also: claims to be "one thing per line", yet allows and encourages multiple events on one line (as long as they're on the same day). This is a calendar - is an event not the main "thing" we're dealing with?!

I use a template [1] that has the dates (including week numbers) there already. That way, I only need a text editor.

In my work, similar events happen on the same week numbers in different years. The importance of week numbers probably depends on your area of work.

For me, one thing is a day. That's also the context I need when reviewing and planning. But if I remember correctly, previous HN thread on calendar.txt had a suggestion where someone had an event-per-line format, if you prefer that.
