Translation guide
The English phrase "the day" can refer to a specific day, a day in relation to an event, or be part of fixed expressions. In Japanese, it is often expressed with the word 日 (hi) or 当日 (tōjitsu), but the exact translation depends heavily on context. Sometimes it is omitted entirely when clear from context.
Referring to a particular day that has been mentioned or is understood from context.

English often uses 'the' before 'day' to specify a particular day. In Japanese, the context often makes it clear, so you may not need a word like その. Overusing その日 can sound unnatural if the day is already obvious.
