Dates#

Dates are displayed differently in different countries, so you must use a date format that’s explicit and consistent and that global users can’t misinterpret.

Unless space is limited, always show dates in the following format: month day, year. Always spell out the month.

Use

Avoid

November 12, 2010

12 Nov 2010

2010-Nov-12

11/12/2010

11/12/10

12/11/10

10-11-12

Note

Don’t use ordinal numbers for dates. For example, don’t use January 1st; use January 1 instead.

When the month, day, and year are embedded in a sentence, use a comma before and after the year. When only the month and year are embedded in a sentence, omit the commas unless the syntax would ordinarily require a comma following the year.

Use

Any sites that are using MySQL 4 after November 1, 2011, will be automatically migrated to MySQL 5.

The Alert Logic Security Research Team used 12 months of security event data captured from July 2010 through June 2011.

As of September 2013, a subset of customer accounts weren’t being billed for actual usage in comparison to their preselected SQL Server storage allocations.

Use an all-numeric date only in the following situations:

  • Space is limited, as in a table or figure.

  • You need to show a literal representation of the date as it’s displayed in the software.

Because all-numeric dates are interpreted differently in different countries, explain the format of a numeric date, and use a consistent format throughout the documentation. If possible, use the ISO 8601 format, which is yyyy-mm-dd (for example, 2012-11-10 for November 10, 2012).

Use

The value that’s shown for 8/19/10 represents the average number of extents from data collections beginning August 19, 2010.
