Which word is formal: agenda, diary, schedule or timetable?

Answer by  Ammy78 (57)

I'd pick agenda as it is applicable in many circumstances. Diary is a little too personal whereas I don't think schedule or timetable sound right in every context.

I'd pick "agenda"--"schedule" and "timetable seem too business-oriented (i.e. I've got the timetable for that project, or We need to make a schedule). "Diary" is too personal, as you'd rarely keep a diary at work. "Agenda" applies in all settings and is the most formal.
