Use Arabic numerals for all numbers. Also use Arabic numerals:
- With units of measure (e.g., “7 miles”)
- For ages (e.g., “age 12 and older”)
- For percentages (e.g., “15 percent”)
In general, avoid using Roman numerals.
When you’re talking about how old someone is, use “age” (instead of “aged” or the “age of” or “years”).
|All children age 7 and older can join this program.|
When talking about an age range, use “ages” and indicate the range with “to” instead of a hyphen.
|This seminar is for adults ages 55 to 65.|
Time and date
Always use Arabic numerals for dates.
|The meeting is on April 5, 2021.||Join us on August 21st.||We’ll see you on 8/20/21.|
When stating time:
- Use “a.m.” and “p.m.” in lowercase
- Drop :00 when listing times on the hour (8 a.m., not 8:00 a.m.)
- Use “to” between ranges of time instead of a hyphen
|We’ll hold the session from 10 to 11 a.m.||Drop-by hours are 10:00 — 11:00 A.M.|
Use hyphens in phone numbers instead of periods or parentheses.
|Call us at 860-500-4412.||Call us at (860) 500-4412.||Call us at 860.500.4412.|
List extensions consistently.
|Call us at 860-500-4412, ext. 707|
When referring to both local and toll-free numbers, put the local number first followed by the toll-free number in parentheses.
|Call us at 860-500-4450 (or 800-282-6063 toll-free outside Connecticut).|
In general, we prefer the verb “call” when providing phone numbers (instead of old-fashioned alternatives like “dial,” which is a leftover from the age of rotary phones). But there’s one important exception. We follow the style of 2-1-1 of Connecticut and always use “dial” when referring to 2-1-1.
