Hi @Erdem_Guner, you’ve probably found a solution already, but sharing mine here anyway as I was facing the same challenge and solved it like this:
start/dateTime gt '{{ new Date('2025-03-20T00:00:00').toISOString().split('.')[0] }}'
and
start/dateTime lt '{{ new Date(new Date('2025-03-20T00:00:00').getTime() + 86400000).toISOString().split('.')[0] }}'
In my use case, I just want to see events per particular day and have AI decide which date to check - just replace the date by $fromAI(‘date_placeholder’).
Mind that the date here gets converted to UTC to align with the calendar.
