What word will literally convey '52 times a year'? [closed]

If I do something twice a year, it's semi-annual. But what if I do something 52 times a year?

I have to send a reminder to my team about our weekly meeting (update their minutes, time, projects, etc). Traditionally, we all add some personal flavor to it. I'm looking to spice it up by referring to the meeting as a [word-meaning-split-into-52]annual meeting.

Additional commentary:

It has been suggested that 'duoquinquagensimannual' may be the proper term. However a search on Google has provided yields only this post, leaving me to believe there may be a more appropriate term.

Additionally, I sent the reminder this morning using the phrase 'Hebdomadal' as suggested. It does accurately convey what the meeting is, while still making it less boring than 'weekly'. (Pff, how boring is weekly?) However, despite its usefulness at solving my business concern, it fails to meet the specific criteria set forth by the request. So it will indeed be useful for anyone else potentially seeking the same phrase I seek, we're unfortunately left with an unanswered question.

Solution 1:

Hebdomadal is the word you want.

Solution 2:

Previously-mentioned hebdomadal ("Weekly, occurring once a week") seems a good choice for referring to the meeting frequency, but for reports and minutes brought to the meeting you might refer to heptameric reports, after the noun heptameron ("A literary work whose action covers a period of seven days").

Solution 3:

But every fourth year, at least, it'll be 53 times, not 52, so what you really need seems to be a word that means "every seven days".

And, as Barrie points out, that's Hebdomadal /hɛb'dɔmədəl/.

This is simply Latin for 'weekly', which is itself from the Greek hebdomas, from hepta, the number 'seven'. Compare Latin septem, 'seven', and other PIE numerals.
