Schedule trigger interval timer

[korovaevda]

Hello everyone! If anyone has encountered this, please help me understand why the scheduled trigger works like this.
I set the interval for launching - every 50 minutes.

The trigger starts after 50 minutes, then after 10 minutes, then again after 50 minutes and then after 10.

Where did the second triggering after 10 minutes come from?
In my understanding, it should trigger like this
at 9:00 - 9:50 - 10:40 - 11:30 … i.e. 50 minutes between triggering
Or am I not understanding something about the mechanism of this node?!

• n8n version - 1.95.3
• self-host version

Hey @korovaevda

Will you be able to share the following information?

• What is your n8n version?
• Are you using self-host or cloud version?
• Screenshot or json file of your workflow?

Best,
Duy

Unfortunately there is no easy way to do this.

It might consider to add a lot of rules if you really want add 50 minutes starting from 9:00

I would understand if the trigger was triggered at 50 minutes every hour
9:50 - 10:50 - 10:50 and so on
I don’t understand why it triggers at both 9:50 and 10:00

I think I figured it out
this is a standard cron job
*/40 * * * *
The */40 field means: starting from minute 0, run the task every 40 minutes within the current hour. That is, cron will run the command at:
00:00, 00:40, 01:00, 01:40, 02:00, 02:40, …, 23:00, 23:40
