As a follow-up to yesterday’s Tip of the Day, today we shall discuss how to express a range of times.
There are two ways to express a time range:
1) Use an en-dash with no spaces on either side of it. Example: 9–10 a.m.
2) Use the “from X to Y” format. Example: from 9 to 10 a.m.
Do not use both or a mixture of the two. Bad Example: from 9–10 a.m.
If the starting time for an event and the ending time are on opposite sides of noon or midnight, you will need to specify a.m. and p.m. next to the respective time. However, if the event is contained entirely in the morning or evening, you will only need to use a.m. or p.m. once.
Breakfast is served 6–9 a.m.
The team meeting will be held in the Visionarium 9 a.m.–noon.
Lunch is served 11:30 a.m.–1:30 p.m. (no “from” and no spaces before or after en-dash)
Dinner is served from 5 to 10 p.m.
The bar is crowded from 10 p.m. to 2 a.m.
Now I’m really hungry.
My personal favorite time range expression is found on a party invitation: 8 p.m.–’til
Although technically it is redundant.
