What is another word for backdates?
Pronunciation: [bˈakde͡ɪts] (IPA) 
"Backdates" is a term that refers to the act of assigning an earlier date to an event than the one on which it actually occurred. Synonyms for backdates include retroactively, retrospectively, antedates, pre-dates, and post-dates. Retroactively means to apply an effect to an event that occurred in the past. Antedates and pre-dates both refer to events occurring earlier in time, with the former indicating that a date has been assigned to something prior to its occurrence, and the latter referring to an event that occurred before a specific date. Post-dates, on the other hand, refer to events that are assigned a later date than their occurrence. Each of these synonyms can be used interchangeably with "backdates," depending on the context in which they are used.
