DateplusWeeks2

DateplusWeeks2 is a small utility name used in programming to describe a function that computes a date two weeks after a given date. It is a naming convention found in various codebases, with similar variants such as datePlusWeeks2 or addTwoWeeks. The concept is simple: return a new date that is exactly 14 days later than the input date.

What it does and how it behaves

The function accepts a date input, which may be a Date object, a timestamp, or an ISO date string, and returns a new date object representing 14 days after the input. In typical implementations, the operation is immutable—the original date is not modified. Adding two weeks is equivalent to adding 14 days, which naturally handles month and year boundaries without requiring manual calendar calculations.

Time zones and precision

Different implementations may operate in local time or in UTC. A robust dateplusWeeks2 should specify its time zone behavior, since DST transitions and time zone changes can affect the time component in some environments. When constrained to date components (year, month, day), the result usually remains consistent across time zones.

Edge cases

Crossing month or year boundaries and leap years are handled automatically by adding a fixed number of days. If input validation is strict, the function may reject invalid dates and return an error or a null value.

Example

Given the date 2023-12-20, dateplusWeeks2 returns 2024-01-03 (two weeks later).
