The acronym you’re probably looking for is TBA or TBD , depending on what you mean. TBA means “to be announced,” and TBD means “to be determined”; both are used when the next event or detail comes after the one before it is set.

If you meant a schedule where items happen one after another, the more common shorthand is just sequential or following , not a single standard acronym. For “scheduled,” common abbreviations are sched. or skd..

In plain English

If your note says an event is “followed by the previous one,” you may be describing an order, not an acronym. In that case, people usually write next , following , or subsequent , rather than using a special abbreviation. Would you like the acronym for a specific context, like calendars, TV listings, or project schedules?
