を限りにFinal cutoff or last occasion
を限りに marks a time or event as the final cutoff. After that point, an activity, service, relationship, or policy ends and does not continue as before.
What the expression tells the listener
The noun before を限りに is not merely a deadline. It is presented as the last relevant occasion or the point at which an ongoing practice ends. For that reason, the sentence should make clear what will stop afterward.
Typical cutoff situations
The expression works especially naturally with personal resolutions, retirement or withdrawal, and the ending of an organizational service.
今日を限りに、毎晩の飲酒をやめます。
Today will be the cutoff: I’m giving up drinking every night.
AnalyzeThis is a deliberate personal resolution, so the emphatic finality is natural.

The close variant
限りで can also place the cutoff directly before the statement of what ends. The central meaning remains that the named point is the last one.

AnalyzeLast occasion or ordinary deadline?
を限りに presents the named point as the last occasion after which something ceases. をもって can mark a similar official cutoff but sounds more ceremonial and announcement-like. までに instead gives a deadline by which an action must be completed; it does not itself say that an ongoing activity ends permanently.
