BC

Bc is an abbreviation that can refer to several different topics, depending on context. It is not a single concept and is typically case-sensitive.

In geography and politics, BC most commonly denotes British Columbia, a western province of Canada. In English-language usage, the province is widely abbreviated as BC in government and everyday writing, with the ISO region code CA-BC used in formal contexts. The capitalization B C in official materials and postal addressing differs from occasional stylizations that may appear in logos or branding.

In historical dating, BC stands for Before Christ, used together with AD (Anno Domini) or BCE (Before Common Era) in modern scholarly writing. The form BC is standard in many Western texts, while Bc is not the conventional representation; when BCE is preferred, BC is typically avoided.

In computing, the lowercase bc refers to a Unix-like arbitrary-precision calculator and language used for mathematical computations and scripting. The capitalized form Bc does not denote the same program and is rarely used in technical contexts.

Other uses of Bc can occur in branding, shorthand for personal or organizational initials, or stylistic abbreviations in specific fields. Because of its varied meanings, the intended reference of Bc typically depends on accompanying context or punctuation.
