Usage notes
Common mistakes
夜以继日 cannot be used with 地 before a verb, unlike 日以继夜. For example, say 他们夜以继日地工作 is correct with 地, but it is actually acceptable; the common mistake is reversing the order. Actually, both 夜以继日 and 日以继夜 exist, but 夜以继日 is more standard and often used in fixed phrases. Clarification: Some learners incorrectly write 夜以继日 as 日以继夜 when intending to mean 'day and night' in strenuous effort contexts. The common mistake is using the reversed order.
Formality
This idiom is formal and typically used in written contexts or formal speeches to describe relentless effort, not in casual conversation.
