You can use an XPath for that. Take a look at the documentation here: https://world.mendix.com/display/refguide6/XPath%20day-from-dateTime First we need not the current date but 5 days before the current date. Create the variable DayToCheck and let this be addDaysUTC([%CurrentDateTime%],-5) Then create two lists. One using the Xpath [day-from-dateTime(Birthdate) = day-of-year-from-dateTime(DayToCheck)] The other list you do the same with the month: [month-from-dateTime(Birthdate) = month-from-dateTime(DayToCheck)]

The persons you are looking for are the persons that are in both lists. You can use the list operation intersect for that. See the documentation here: https://world.mendix.com/display/refguide5/List%20Operation

Good luck

Regards,

Notifications themselves are easy. Simply use the action 'show message', with a content of choice.

When to show them is the interesting bit. You say you need these messages to show on the homepage, five days in advance, so I take it we're looking at a dateTime variable here. I'll take your facebook birthday as an example.

The easiest way is to always open your homepage using a microflow. In this microflow, you retrieve the account for the user (which in your example should contain a date of birth). Use an exclusive split to check whether the difference between [%currentDateTime%] and Account/birthday is 5 days or less. If so; show message. If not, proceed as normal.
