A Future ArM 6 -- what is ESSENTIAL?

It is indeed an issue of educated reading.
(1) Measuring spell durations by solstices and equinoxes has nothing to do with medieval or modern calendars, with their beginnings, ends and even lengths of days depending on place, culture and education of the speaker.
(2) So solstices and equinoxes are astronomical events.
(3) So a sunrise on such an event is the sunrise following it.

1. Never said it did.

Good.

@Jonathan.Link

2. Solstices also refer to the day of the event, and have, for quite some time.

That day, however, is defined by a calendar. In history days have begun at midnight, at sunrise, or at sunset. A reference "to the day of the event" is culture specific even within Mythic Europe - and not useful for Hermetic magi measuring spell duration time.

@Jonathan.Link

3. Can you demonstrate that? I've never read that in any academic historical text. Can you provide such a reference?

I thought you knew (see Heroes' Birthright: duration and warping):

Astronomical solstice or equinox is not a day, but a point in time. The sunrise on a point in time is the sunrise following it.

I know.
