how to prevent spring batch job from running on particular day?

Question

0 0 0 25 12 ?

this cron expression runs on every Christmas Day at midnight. I want to prevent it from running on Christmas Day.

Answer 1

since you can define cron expressions only when they should run and not when they shouldn't run, i see only two options here:

1. check the current Date within your task/job and if its Christmas Day, skip execution
2. define a / multiple cron(s) that run on every other day than Christmas
   #runs every day starting january till november
   0 0 * * 1-11 *
   #runs every day in december except at the 25th
   0 0 * 1-24,26-31 12 *
