trysting

An appointment; a tryst.

Trysting day, an arranged day of meeting or assembling, as of soldiers, friends, and the like.

And named a trysting day,
And bade his messengers ride forth
East and west and south and north,
To summon his array.

-- Trysting place, a place designated for the assembling of soldiers, the meeting of parties for an interview, or the like; a rendezvous. Byron.
