Both Days
noun
Kanji doesn't go together much better than this. Both plus day equals both days.
This is a bit of a formal word though, you'll hear important people say it more than your friends.
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 日 has two on'yomi readings, here's a mnemonic to help you remember which one to use:
On both days of your vacation, you get two boats to row! Gee, two (りょうじつ) boats at once? Try not to fall in!
両日とも雨

両日とも休日

両日とも４:00まで

両日のスケジュールをメールして下さい。

ごめんなさい。両日とも、ミーティングが入っています。
