About をもって

When used with time related expressions, the structure をもって is often translated as 'as of (A)', or 'effective from (A)'. This grammar pattern is a construction of the adverbial particle を, and もって 'by means of'.
をもって will be used after nouns that indicate a time, or an event that happens at a specific time.

As is frequently seen in polite speech or in official notifications, をもって may sometimes be read as をもちまして.
  • いつもご来店(らいてん)ありがとうございます。この店舗(てんぽ)本日(ほんじつ)をもちまして閉店(へいてん)いたします。

Although 'effective from' can have the nuance of 'starting' in English, をもって primarily focuses on something ending, or what has happened up until the end date specified. Due to this, it will not be used to indicate that something is starting from a date that had nothing significant happen before it.
  • 2023(ねん)7(がつ)27()をもって人気(にんき)映画(えいが)続編(ぞくへん)公開(こうかい)されます。

Fun Fact
Coming from the kanji (もっ)て, and specifically meaning 'by means of', もって originally derives its nuance from ()って, 'to hold', or 'to have'. In this way, it may help to remember もって as working in a similar way to 'having (A)', or 'having reached (A)' in English.
