How Many Days
What Day, Which Day
noun, expression
What day equals the fairly obvious translation "what day." But, it also means how many days.
This is a jukugo word, which usually means on'yomi readings from the kanji, but 何 actually uses the kun'yomi reading here! And since 日 has two on'yomi readings, here's a mnemonic to help you remember this reading:
