Every year, all my family members celebrate their birthdays on the same day of the week.
ご質問ありがとうございます。
「家族の[誕生日](https://eikaiwa.dmm.com/uknow/questions/44586/)が毎年全員同じ曜日です」は英語で「Every year, all my family members celebrate their birthdays on the same day of the week.」と言います。
まず、「Every year」は「毎年」という意味です。
そして、「all my family member celebrate their birthdays」は「家族の誕生日が全員~」を表します。
最後に「on the same day of the week」は「同じ曜日です」という意味です。
ご参考になれば幸いです。
All of my family members' birthdays are on the same day of the week every year.
"家族の誕生日が毎年全員同じ曜日です。"
- All of my family members' birthdays are on the same day of the week every year.
- My family’s birthdays land on the same day of the week every year.
家族の誕生日が全員7の倍数の日数離れているので、家族全員の誕生日が毎年同じ曜日になります。
- Since all members of my family have birthdays separated by multiples of 7 days, all of our birthdays fall on the same day of the week each year.
