Ludwig's WRAP-UP

The phrase "since three weeks ago" is a grammatically correct adverbial phrase used to specify a duration from a point in the past until the present. Ludwig AI confirms its validity. While it's not as common as simpler alternatives like "three weeks ago" or "for the past three weeks", it serves to set a clear timeline. It's essential to use it to denote a continuous period, not just a single point in the past, as doing so could lead to confusion. Ludwig's analysis shows it appears mostly in news and wiki articles.
