oneyear

Onyear, written as one word, may refer to the concept of a one-year period. In general use, "one year" denotes the duration from a point to the same date one year later, typically approximately 365 days, depending on calendar systems. The concatenated form "oneyear" is often seen as an identifier in software, databases, or branding.

In the Gregorian calendar, a common year has 365 days, while a leap year has 366 days. A tropical year, the cycle of seasons, is about 365.2422 days. Because of leap years, most one-year periods span either 365 or 366 days when measured from date to same date.

One-year periods are used in contracts, warranties, subscriptions, and project planning. Terms such as "one-year term" or "one-year warranty" specify duration.

In computing and data contexts, "oneyear" can be used as a variable or code to indicate a duration or cycle of twelve months. The concept also appears in time-series analysis and calendar applications.
