The Roman convention of closing a document by writing "given" and the day and month (meaning "given to messenger") led to data becoming a term for "the time stated."

Skt. gâtu- "going, motion; free space for moving; place of abode;" PIE *gwem- "to go, come") + dâd "given," as in Latin; p.p. of dâdan "to give" (Mid.Pers. dâdan "to give," O.Pers./Av. dā- "to give, grant, yield," Av. dadāiti "he gives," Skt. dadáti "he gives," Gk. didomi "I give;" akin to L. data, as above); cf. Mid.Pers., Mod.Pers. dâd "year, age, period of life," Lori, Laki dâ(d) "age," homdâ "of equal age."
Note: In current Persian a single term, târix (تاریخ), is used for two different but related concepts: date and history. This may be confusing, → history (تاریخ).

'y'b "to attain," Parthian, Sogdian (+ *pati-) pty'b "to reach, obtain," Av. ap- "to reach, overtake," apayeiti "achieved, reached," Skt. âp- "to reach, gain," âpnoti "reaches, gains," Gk. hapto, haptomai "to touch, cling to, adhere to," L. apiscor "touch, reach;" PIE base *ap- "to take, reach."

dative case
  کاته‌ی ِ برایی

Fr.: cas datif   

The form of a word (in Latin and other inflected languages) indicating the noun or pronoun for which an action happens or a quality exists. In English loosely used for → indirect object (for example, him in Give him the book).

From L. casus dativus ("case for giving"), a translation of Gk. dotike ptosis ("inflection for giving"), from dativus "pertaining to giving," from datus "given" (from PIE root *do- "to give"), → datum; → case.

Kâte, → case; barâyi, adj. of barâye, "→ because of," "→ for."

L. datum "given," neuter p.p. of dare "to give, offer," cf. Av. and O.Pers. dā- "to give, grant, yield," Av. dadāiti "he gives," Skt. dadáti "he gives," Gk. didomi "I give," PIE base *do- "to give."

Dâdé "given," p.p. of dâdan "to give," Mid.Pers. dâdan "to give," O.Pers./Av. dā- "to give, grant, yield," akin to L. data, as above.
