CarbonAvailability

Given some available times and some unavailable times how do you determine what time slots you can schedule an event of a certain duration (think something like calendly)? Well – it's surprisingly hard – unless you're using this.

use Braid\CarbonAvailability;

/**
 * [==========]                            | Available time blocks
 *               [========]                |
 *                        [==========]     | ______________________
 *                    [xxxxxxx]            | Booked time blocks
 *                                [x]      | ______________________
 * [==========] [====]         [=]         | Merged availability
 * |  |  |  |   |  |           |           | Available sessions
