When to use it

Has two main uses. 1) The end or start point of something official: 本日ほんじつをもって閉店へいてんします (we close as of today). 2) The means or basis: 書面しょめんをもって通知つうちする (notify in writing). Used in announcements, ceremonies, letters, store notices and formal business documents, and heard at the end of school or company events.

Nuance

Very formal. をもちまして is the polite spoken form for speeches and announcements (これをもちまして閉会へいかいいたします). Rarely used in casual talk. For the time meaning, it usually marks an official deadline, end of service or closing.

Compare

で is the everyday version of both uses: 今日きょうで終おわり, メールで知しらせる. をもって raises the register for official contexts. を限かぎりに also marks an end but stresses that this is the very last time: 今日きょうを限かぎりにやめる.

Tip: Learn the set phrases: これをもちまして, 本日ほんじつをもって, 書面しょめんをもって. These set phrases cover most of what appears on the test.
