Time
When time must be formatted manually, follow these guidelines:
- Use the 12-hour clock, followed by am or pm.
- Include a space after the last number. For example, “Your package will arrive at 12:35 pm.”
- To show a time range, use an en dash (-) and include the am/pm after both times. Example: 3:00 pm–4:00 pm.
- If indicating both the date and time, separate them with the word “at” instead of a comma. Example: November 23rd, 2022 at 3:00 pm.
Currency
When including currency with a price, place the currency sign after the amount. If a currency has no symbol, use the same format but do not add a symbol.
| Examples |
|---|
| $10,000 USD |
| €10,000 EUR |
Numbers
When using numbers, avoid spelling the number.
| Do | Don't |
|---|---|
| 5 notifications | Five notifications |
| You have 2 new items in your cart | You have two new items in your cart |
Where possible, truncate numbers and avoid using commas.

| 121K | 121,000 |
| 1.2M | 1,200,000 |
| 1B | 1,000,000,000 |
Number ranges
Use an en-dash (-) without a space on either side for number ranges.
| Examples |
|---|
| 1-5 items |
| $10.00–$19.99 |
| 1994–2004 |
Use “to” instead of an en dash if a number range is preceded by “from” in a phrase. Use “and” if a range is preceded by “between.”
| Examples |
|---|
| Active from September 10 to September 28 |
| A delivery is scheduled from 10:00 am to 2:00 pm on Monday, July 18. |
| 1994–2004 |
