Filter articles by date range using custom date fields

Ok. But I can't add fixed date/time to start date. date/time value is always differente.
Please add this as a feature request.

no you can choose field for starting date its always dynamic and you can add offset for end (statics)

Sorry I didn't explain properly, I would need a dynamic offset.
The difference in days between start date and end date can be different, depends on the event.
For example one event can be from 05/09/2016 to 07/09/2016 other can be from 05/09/2016 to 12/09/2016.

Could you add this in a future release ?

Micker, let me explain, some events have 2 sets of DATES:
* Beginning Date
* End Date

Let's say I have 2 events:
* Event 1 - It goes from 1 January until 31 January
* Event 2 - it goes from 10 Jan until 12 Jan

In the module I want to show event until the END DATE, so how can I configure this?
* If I say to show the event based on the FROM DATE and I set a limit of 31 days after their started the EVENT 2 will show after it finished
*If I say to show the event based on the FROM DATE and I set a limit of 2 days after finished EVENT 2 will be ok but EVENT 1 will disappear

We need to have the possibility to configure it like this:
SHOW EVENT using the FROM DATE including TODAY and remove them 1 day after they finished.
|_ Flexicontent does not allow this or does it?

not but we can add it can you open a github issue with your description ?
