Ludwig's WRAP-UP
The phrase "past year" is a grammatically correct and highly versatile temporal marker. According to Ludwig AI, it is most effectively used to describe a rolling 12-month period, distinguishing it from "last year", which typically denotes a specific calendar year. High-authority sources like The Economist and The New York Times frequently employ it to contextualize trends in business and politics. When using "past year", writers should ensure that the context supports a rolling duration rather than a fixed calendar block to maintain clarity and precision in their narrative. For even greater technical accuracy, alternatives like "past twelve months" may be substituted.
