-Finally, you can also alter the date range with which the application will fetch vaccination slots by customising **DATE_RANGE** value in [`src/configs/schedulerConfig.js`](https://github.com/sinhadotabhinav/covid-19-vaccine-alerts-cowin/blob/master/src/configs/schedulerConfig.js) file. By default it is set to **7** but, you can change it to 10 or 15 for example, based on your need. The config file also allows changes in the periodic schedule with which the application runs. By default, **SCHEDULE** value depicts a cron schedule **every hour at minute 5 and second 0**. To alter this schedule, you need to be familiar with the [cron scheduler](https://linuxhint.com/cron_jobs_complete_beginners_tutorial/#:~:text=The%20scheduled%20commands%20and%20scripts,Task%20Scheduler%20in%20Windows%20OS). I use [Crontab Guru](https://crontab.guru) website to test my cron schedules.
