Create event daily, on a specific time - events

Question

First event deletes all rows from a table:
CREATE DEFINER=`frontdes_user`#`localhost` EVENT `DELETE_flux_receptie` ON SCHEDULE EVERY 1 DAY STARTS '2015-09-06 00:00:00' ON COMPLETION PRESERVE ENABLE DO DELETE FROM `flux_receptie`
Second event deletes the id column from the same table:
CREATE DEFINER=`frontdes_user`#`localhost` EVENT `delete_id` ON SCHEDULE EVERY 1 DAY STARTS '2015-09-06 00:00:00' ON COMPLETION PRESERVE ENABLE DO ALTER TABLE `flux_receptie` DROP `id`
Third event adds id column into the same table:
CREATE DEFINER=`frontdes_user`#`localhost` EVENT `add_id` ON SCHEDULE EVERY 1 DAY STARTS '2015-09-06 00:00:00' ON COMPLETION PRESERVE ENABLE DO ALTER TABLE `flux_receptie` ADD `id` INT NOT NULL AUTO_INCREMENT FIRST, ADD PRIMARY KEY (`id`)
I want these events to run daily:
First one daily at 06:30, the second one daily at 06:35 and the third daily at 06:40.
Can anyone help me please with the correct schedule? Best regards, Bogdan.

If you have access to your machine you can use cronJob, the basic format of a crontab schedule consists of 6 fields, placed on a single line and separated by spaces, formatted as follows:
minute hour day month day-of-week command-line-to-execute
first create a script:
First script
#!/bin/bash
mysql --user=[username] --password=[password] --database=[db name] --execute="CREATE DEFINER=`frontdes_user`#`localhost` EVENT `DELETE_flux_receptie` ON SCHEDULE EVERY 1 DAY STARTS '2015-09-06 00:00:00' ON COMPLETION PRESERVE ENABLE DO DELETE FROM `flux_receptie`"
Second script
#!/bin/bash
mysql --user=[username] --password=[password] --database=[db name] --execute="CREATE DEFINER=`frontdes_user`#`localhost` EVENT `delete_id` ON SCHEDULE EVERY 1 DAY STARTS '2015-09-06 00:00:00' ON COMPLETION PRESERVE ENABLE DO ALTER TABLE `flux_receptie` DROP `id`"
Third script
#!/bin/bash
mysql --user=[username] --password=[password] --database=[db name] --execute="ALTER TABLE `flux_receptie` ADD `id` INT NOT NULL AUTO_INCREMENT FIRST, ADD PRIMARY KEY (`id`)"
then create 3 cron using crontab -e
crontab -e
30 6 * * * /path/of/scriptOne
35 6 * * * /path/of/scriptTwo
40 6 * * * /path/of/scriptThree
