Hi RamChandangar,

Peak hours are from 6.30 - 9.00 am and from 4.00 - 6.30 pm. There's a 5 minute margin, so you can check-in and travel for free until 4.05 pm. You were one minute too late unfortunately.

ps Wordt Almere Buiten in het Engels nou echt weergegeven als Almere Outside?! 
(Is Almere Buiten really translated as Almere Outside?!)

hi there,  i saw this helpful info. 

But to my understanding,  the picture shows that the checkin time was 4:05. Why does it not count as the free dal vrij?  If you say 5-min margin,  i think this case is free.  If I checkin at 4:06, i would be 1min late.  Could you please help to ask me?  Thanks 

It is free until 4:05 pm, not until and including. So you can check in at 4:04 and 59 second to travel free with Dal Vrij. Once the clock says 4:05 pm it is too late to travel free. 

The margin is 5 minutes so when the clock changes to 4:05 pm (or 16:05 on the screen) the margin has expired.

In other words, with the (unofficial) 5 minutes margin, peak hours start at 16:05:00
