1Q

1q is an alphanumeric term used in several fields to denote different concepts, depending on context. It does not have a single, universal meaning.

In genetics and cytogenetics, 1q denotes the long arm of chromosome 1. Cytogenetic labeling uses the letter q to indicate the long arm, with numbers following to specify regions or bands, such as 1q21.1. Descriptions of chromosomal abnormalities often reference 1q in relation to location and extent.

In finance and business reporting, 1Q (often written as 1Q or 1Q202X) stands for the first quarter of a fiscal year. This period typically covers the initial three months of the year for many companies, though fiscal calendars vary by organization. Earnings, revenue, and other metrics are commonly reported for 1Q.

In literature and popular culture, the stylized title 1Q84 is a well-known example. Published by Haruki Murakami in 2009–2010, the work uses the combination of a numeral and the letter Q as part of its title.

In sports and media scoring, 1Q can appear as an abbreviation for the first quarter of a game, especially in score tables or logs. However, Q1 is the more common convention in most contexts.

Other uses include various product codes, model numbers, or data annotations where 1q serves as a shorthand for “one quarter” or as an identifier within a larger labeling system. Because 1q can refer to multiple, unrelated concepts, its precise meaning is determined entirely by the surrounding context.
