Hodiernal tenses refer to events of today (in an absolute tense system) or of the day under consideration (in a relative tense system).

Hodiernal past tense refers to events of earlier today (or earlier than the reference point of the day under consideration), while hodiernal future tense refers to events of later today (or later than the reference point of the day under consideration). Post-hodiernal tense is a future tense for events that will occur after today or the day under consideration, while pre-hodiernal is a past tense for events that occurred before today or the day under consideration.
