## Description

This is a PHP library and scheduling utility used to parse cron expressions and calculate execution dates. It functions as a cron schedule calculator that determines the next run date and execution iterations from standard cron strings.

The project provides capabilities for predicting future run dates and calculating sequences of upcoming timestamps. It also includes a utility to verify if a scheduled task is currently due for execution by comparing the system time to a cron expression.
