java - quartz scheduler: run on last day of the month and few other days -


i want run job on 3rd , last day of month.

is following cron expression correct ?

"0 0 3 3,l * * ?"

when try in www.cronmaker.com says it's invalid expression.

the main point of question if can use "l" (representing last day of month other days)

if not, how can express using cron ?

the correct format should

0 0 0 3,l * ? * 

but correctly state cromaker.com not seem it.

if used 2 crons

0 0 0 3 * ? * 0 0 0 l * ? *

it work
