How to add two weeks to the current date

Dear all,Please I am a novice to ODK. Currently I'm working on a
questionnaire and I have reached a place where I suppose to add two weeks
to the current date.How Could I do it?

with the newest ODK Collect 1.4, you can do

calculate="date-time(decimal-date-time(${dateField})+14)"

Note that there are several issues with preserving the time portion of a
date during calculations like this, so you may or may not be able to
preserve the time-of-day.

In the above, I mean put the

date-time(decimal-date-time(${dateField})+14)

in the 'calculation' column of the XLSForm.

I was mixing the constructions in the XML and XLS

Dear esteemed
I am working on an ODK XLS form and I wish to calculate the difference between two datefields and then divide by 7.
I would love the answer to be rounded up

In excel it would look like this (x1-x2)/7.
The idea is to get the number of weeks.
Kindly help.thanks

Date arithmetic in ODK Collect has several bugs that can lead to off-by-one
errors (particularly when working in different time zones or transitioning
between daylight savings time and standard time); time arithmetic is even
less certain.

Be sure to test your form to make sure it works as you expect.

That said, there are a number of functions for date arithmetic. See:

https://opendatakit.org/help/form-design/binding/

in particular, "date, dateTime, time as number"
