Arcane/obscure word that represents a person's timeline or daily record

I'm looking for an arcane or obscure word to describe a person's daily record.

Words like:

account, agenda, appointment book, chronicle, diary, daily record, daybook, engagement book, journal, log, minutes, notebook, record

work, but are common. Do you have something more obscure?

Ephemeris has an obsolete meaning synonymous with this, and it certainly has a solid arcane flavor to it. Also rather lovely is noctuary, which is the opposite of "diary", logging what happens during the night rather than the day.

How about the Latin libellus.

It is used for any "little book", but specifically journals, diaries, logbooks, notebooks.

It's not a very good fit in meaning, but vade mecum springs to mind - literally, it's Latin for "go with me", and it means a little book with useful information that you carry around with you. It can contain a section for daily notes and such, although that is not its primary purpose.
