cronrange

cronrange is a Go package for time range expression in Cron style.

In a nutshell, CronRange expression is a combination of Cron expression and time duration to represent periodic time ranges, i.e. Cron for TimeRange. And it made easier to tell if the moment falls within the any time ranges (use IsWithin() method), and what's the next occurrence (use NextOccurrences() method).

For example, every New Year's Day in Tokyo can be written as:

DR=1440; TZ=Asia/Tokyo; 0 0 1 1 *

It consists of three parts separated by a semicolon:

• DR=1440 stands for duration in minutes, 60 * 24 = 1440 min;
• TZ=Asia/Tokyo is optional and for time zone using name in IANA Time Zone database;
• 0 0 1 1 * is a cron expression representing the beginning of the time range.
