Definition
日以继夜 is a four-character idiom meaning 'day and night' or 'round the clock'. It describes doing something continuously without stopping, often for work or study. The literal reading is 'day continuing into night'. You can use it adverbially before a verb, e.g., 日以继夜地工作 ('work day and night'). It's more formal and emphatic than 日夜.
