# Overview

An

*Interval*

represents the period of time between two

*Instant*

s.

Refer to

Interval

on Joda-Time site for further details.

- Construct An Interval
- Find Relationship Between Two Intervals (Gap, Adjoining, Overlap)
- Modify Interval Using Millis, Duration and Instant

#### Construct An Interval

Interval can be constructed in the following six ways:

- Using start and end milliseconds
- Using Duration and Start/End Instant
- Using another Interval
- Using Start and End Instants
- Using Period and Start/End Instant
- Using String Representation

#### Find Relationship Between Two Intervals (Gap, Adjoining, Overlap)

The following relationships can exist between two intervals:

- Adjoining (a.k.a abut): Are the two intervals adjoing to each other
- Gap: Do the two intervals have gap between them
- Overlap: Do the two intervals overlap each other

#### Modify Interval Using Millis, Duration and Instant

An

*Interval*

can be modified in the following ways:

- Modifying start and end using millis
- Modifying start and end using Duration
- Modifying start and end using Instant
