Grammatical tense
Possible tenses

Not all languages have tense: tenseless languages include Chinese and Dyirbal. Some languages have all three basic tenses (the past, present, and future), while others have only two: some have past and nonpast tenses, the latter covering both present and future times (as in Arabic, Japanese, and, in some analyses, English), whereas others such as Greenlandic, Quechua, and Nivkh have future and nonfuture. Some languages have four or more tenses, making finer distinctions either in the past (e.g. remote vs. recent past) or in the future (e.g. near vs. remote future). The six-tense language Kalaw Lagaw Ya of Australia has the remote past, the recent past, the today past, the present, the today/near future and the remote future. Some languages, like the Amazonian Cubeo language, have a historical past tense, used for events perceived as historical.

Tenses that refer specifically to "today" are called hodiernal tenses; these can be either past or future. Apart from Kalaw Lagaw Ya, another language which features such tenses is Mwera, a Bantu language of Tanzania. It is also suggested that in 17th-century French, the passé composé served as a hodiernal past. Tenses that contrast with hodiernals, by referring to the past before today or the future after today, are called pre-hodiernal and post-hodiernal respectively. Some languages also have a crastinal tense, a future tense referring specifically to tomorrow (found in some Bantu languages); or a hesternal tense, a past tense referring specifically to yesterday (although this name is also sometimes used to mean pre-hodiernal). A tense for after tomorrow is thus called post-crastinal, and one for before yesterday is called pre-hesternal.

Another tense found in some languages, including Luganda, is the persistive tense, used to indicate that a state or ongoing action is still the case (or, in the negative, is no longer the case). Luganda also has tenses meaning "so far" and "not yet".

Some languages have special tense forms that are used to express relative tense. Tenses that refer to the past relative to the time under consideration are called anterior; these include the pluperfect (for the past relative to a past time) and the future perfect (for the past relative to a future time). Similarly, posterior tenses refer to the future relative to the time under consideration, as with the English " future-in-the-past ": (he said that) he would go. Relative tense forms are also sometimes analysed as combinations of tense with aspect: the perfect aspect in the anterior case, or the prospective aspect in the posterior case.

Some languages have cyclic tense systems. This is a form of temporal marking where tense is given relative to a reference point or reference span. In Burarra, for example, events that occurred earlier on the day of speaking are marked with the same verb forms as events that happened in the far past, while events that happened yesterday (compared to the moment of speech) are marked with the same forms as events in the present. This can be thought of as a system where events are marked as prior or contemporaneous to points of reference on a timeline.
