“I was born on a Thursday.”
“To be born” is the passive voice of the word “bear”. You could say something like, “My mother bore three children.” But it is not common to hear “bear” in the active voice. Usually we just say, “She had three children.”
「私は木曜日に産まれました。」
「To be born」（産まれる）は「bear」（産む）の受け身の形です。「私の母が三人子供を産んだ」などとは言えますが、「bear」を能動態で使うのは少し珍しいです。普段は代わりに「have」を使います。
