Cron Generator is a complete straightforward application to generate and test Cron expressions valid for Quartz's Cron triggers and similar tasks.
The application is divided in 7 sections to facilitate the creation of the expressions: minute, hour, day, week, month, year and a section to test custom Cron expressions.
Every section guide you in creating a valid expression and shows the first occurencies from the current starting time (up to 50 repetitions). It's also possible to easily copy the expression to use it in other applications.
Comments and suggestions are very welcome, feel free to leave your opinion.
