香港志錄現時共 36501 條，其中只有 8766 條精確到日 —— 即係可以用嚟做日期頁嘅全部。 其餘條目原文只寫到年份或者月份，唔會被強行塞入某一天。
志錄只收已出版卷冊，所以「呢日有 9 條」唔代表「香港喺呢日只發生過 9 件事」， 而係「已收錄嘅卷冊之中，有 9 條可以對到呢一日」。未收錄嘅年份唔會補，亦唔會用鄰近日期頂替。
The archive holds 36501 entries, of which 8766 are dated to an exact day — those are the only ones used here. Entries dated only to a month or a year are never forced into a day. Coverage reflects published volumes only; missing years are not filled in.
