data
A plural noun, it normally takes plural verbs and pronouns.

dates

  • days 
    Do not abbreviate except when necessary for tabular format. Abbreviations are always three letters without periods (Sun, Mon, Tue, Wed, Thu, Fri, Sat).
  • range of years
    See academic years.
  • Capitalize the names of months in all uses. When a month is used with a specific date, abbreviate only Jan., Feb., Aug., Sept., Oct., Nov., and Dec. Spell out when using alone, or with a year alone. When a phrase lists only a month and a year, do not separate the year with commas. When a phrase refers to a month, day, and year, set off the year with commas.
    Examples: January 1972 was a cold month. Jan. 2 was the coldest day of the month. His birthday is May 8. Feb. 14, 1987, was the target date. Ordinal numbers (i.e., ending in th, nd, rd, st) are used only without the month.
    Note: Do not use superscript for ordinal numbers; use lowercase text instead. To change this preference in Microsoft Word, go to the Tools drop-down menu; Auto Correct; Autoformat as you type, then uncheck “ordinals with superscript”.
    Correct: We’ll see you on the 12th. We’ll see you on December 12. Incorrect: We’ll see you on December 12th.
