How to calculate the difference between dates

[caiqueq]

I need to know the number of days between today and the date of birth

You can use a clock. You can get the duration with the duration() block. The start will be the birth date, and the end will be the now() block. The images are down below.

Time Format Extension - Millis to [HH:mm:ss] - [days + HH:mm:ss] - [HH:mm] - [mm:ss] etc

Here is an extension to format the time / duration (millis) in different ways: → [ HH:mm:ss ] → [ days + HH:mm:ss ] → [ HH:mm ] → [ mm:ss ] → etc. This is asked very often and always requires a lot of questions / answers and posts in the forum. (Last here: Creating a Chronometer - #17 by PizzaGuy07) Hence this extension (some of it can also be implemented with the on-board methods, but I want to simplify it:): Version 1 (May 20, 2020): TFormat.aix (5.5 KB) Version 2 (Oct 20, 2021): TForm…
