Dear experts,I get a problem with my date question.  I put {date("Y-m-d",strtotime("today")-60*60*24*30*2)} and {date("Y-m-d",strtotime("today"))}as the minimum and maximum  limit values of the date but when I answer questions with correct date,  the question warned that the inputed date is incorrect.  Maybe it's a bug in the 3.28 version? May I get your help? Thanks in advance! 

You write Y-m-d in your code, but you show d-m-Y, what is that about?

Hi holch, it seems to depend on my input format, but this is not the reason. I've changed my input format to yyyy-mm-dd but the problem still remains.

1. option:
min date: "-60 days"
max date: "now"

2. option
min date: date("Y-m-d",strtotime('now')-60*60*60*24)
max date: date("Y-m-d",strtotime('now'))

Thanks a lot, Joffm, it works now! The problem is caused by using"today" instead of "now".
