〜を限りに (~o kagiri ni) — as of ~ (and never again)

'Today is the last time — from tomorrow, never again!'

Formula (सूत्र ढाँचा)

N + を限りに

On New Year's morning your friend slaps the table: 「今日を限りにタバコをやめる！」— 'today is the last day; from tomorrow, never again!'.
It works for your own vow and for a notice that a service is ending.

「〜を限りに」= a firm declaration: 'up to this point only — after that, it ends for good'.
What follows is always something ending: やめる・引退する・終了する・〜ない.

N2You met 「限り」(力の限り・知っている限り), and may have heard 「今年限りで辞めます」(only until the end of this year) — 「限りで」just gives the cut-off; 「を限りに」carries the force of a decision: 'that's it!'.
The next point, 「をもって」, also marks an end, but only as an official announcement from an office or at a ceremony; 「を限りに」works just as well for a personal vow.

Starting something (× 今日を限りにジョギングを始める) does not fit — nothing begins after 'the last day'.

今日を限りに、夜中のラーメンはやめることにした。

きょうをかぎりに、よなかのラーメンはやめることにした。

As of today, I've decided to give up late-night ramen for good.

How it is built (कसरी बन्यो) 今日 = today (a time noun) → 「を限りに」 = making today the last → then the thing that ends: やめることにした (decided to quit).

あの選手は今シーズンを限りに現役を引退すると発表した。

あのせんしゅはこんシーズンをかぎりにげんえきをいんたいするとはっぴょうした。

That player announced they will retire at the end of this season.

How it is built (कसरी बन्यो) 今シーズン = this season → 「を限りに」 = making this season the last → then 現役を引退する (retire from playing) — announcing an end.

子どもたちは声を限りに応援歌を歌った。

こどもたちはこえをかぎりにおうえんかをうたった。

The children sang the cheering song at the top of their voices.

How it is built (कसरी बन्यो) 声 = voice → 「を限りに」 = to the limit of one's voice (a fixed phrase) → as loudly as possible → 応援歌を歌った.
