Post-hoc poetry.

I had an idea for a new sub-anthology, details will follow if it actually gets anywhere. It's 13 poems, all based (loosely) around certain things that have happened at uni. I don't want to give too much away in case I decide I hate them all after they're written and they never see the light of day (although the first two that I wrote have been shown to one of my best friends).

Problem is, the idea came afterwards. I'm writing poetry post-hoc and it's causing some problems with dating and ordering the poems in the anthology.

I've tried to order them chronologically based on when the original events happened. This has taken some time and pouring over my diary trying to figure out what nights out happened when and when certain information become public and it's not been easy trying to put events with times.

But I think I've managed it, the last date just fell into place; remembering being filled in about the details of a weekend when I wasn't at uni.

I date my poetry. I've said this before in my post that was purely about poetry, and the date I include is usually the date that the poem is written in first draft form. But these poems are different.

The question I have is: Do I date the poems based on their first draft completion, or do I give them the date from when the event they're based on happened?

I could just include both, but that seems like a cop out. If you have any thoughts, please let me know.
