🤝 Join With Concat
The following is a quick explanation of the concat function in Notion. If you want to join properties or complicated calculations with text properties, this function will be very useful inside your Notion formula.
The First Scenario → Below are a few examples of how concat can be used. The first is a scenario where years, months, weeks, days, hours, minutes, seconds and milliseconds are calculated from the birth date of three individuals. At the end of the table, I provide a clean way to present multiple property formulas into one concat expression.

Formulas (other functions used: dateBetween)
Weeks from birth:
concat(prop("Name") + " is " + format(dateBetween(now(), prop("Born"), "weeks"))) + " weeks " + "old" Clean concat (last property):
concat(prop("Name") + " is " + format(dateBetween(now(), prop("Born"), "years")) + " years, " + format(dateBetween(now(), prop("Born"), "months")) + " months, " + format(dateBetween(now(), prop("Born"), "weeks")) + " weeks, " + format(dateBetween(now(), prop("Born"), "days")) + " days " + "old") The Second Scenario → This scenario showcases a shipping center that wants to create a specific and consistent message layout for to its customers upon ordering their products. They want the following structure to appear: "Your shipment has been fulfilled for the following items: [INSERT ITEMS]. Estimated delivery is [INSERT DAY OF WEEK], [DATE] between 7am and 4pm.
