Hi @alaa-yahia,
I noticed two issues with the Age field:

1. When selecting a date from the calendar, the year, months, and days are filled with incorrect values. (i.e. In the video below, I selected today's date from the Ethiopian calendar, so the year, months, and day should have been filled with 0).
2. When typing a value into the days field, the calendar is filled with the gregorian value of the date.

In the video above I used the Ethiopian calendar. Can you have a look? Thank you!

A good start, but some things we will have to work a bit more on.

In addition to the individual comments we should convert the "last updated" tooltips from ISO to local calendar (I saw this in both the stages and events Widget and the enrollment Widget). Had a very quick look at the stages and events Widget and for now I think you can use something like moment(fromServerDate(updatedAt)).toISOString() and put the result into the clientToView converter of type DATETIME (we should probably also use the serverToClient converter, but this will be checked and resolved in separate ticket)
