Used to emphasize the entire period from the past to the present. Often followed by past tense verbs or potential forms.
Use 今までに when you want to emphasize the entire period from the past to now. For single past events, use かつて or 以前に. For future plans, use 今後.
The verb following 今までに must be in past tense or potential form (e.g., 食べた, 会った, できる). Future tense verbs (e.g., 食べる, 会う) are incorrect.
Combination of 今 (now) + まで (until) + に (particle indicating time). The phrase evolved from literal temporal expressions to its current usage emphasizing the entire past-to-present duration.
1) Always used with past tense or potential form verbs. 2) Cannot be used with future tense. 3) Often used in formal contexts or when emphasizing the entire duration.
