I have a question about the definition entry of "to" in this dictionary.
Definition 11a of "to" reads:
until a particular time or date
Definition 11b of "to" reads:
used for saying how much time passes before a particular date, time, or event
An example sentence under definition 11b reads:
Sales increased during the 13 weeks to September 30th.
Does anyone think that this sentence probably fit better under definition 11a instead of definition 11b? Definition 11a seems to emphasize the period of time, and definition 11b seems to emphasize the point in time.
