Adding workdays to a date

[yoga raja]

Hi all!!

I am a newbie to Appinventor. I would really appreciate if someone could help me in buiding blocks for the following:

1) User enters a date (with date picker)

2) user enters a textbox with a number (no of treatment days)

3) after entering  a number, result should be displayed  as date. 

(i.e. User entered date + no of treatment days = last treatment date) 

Thanks in advance

You say "workdays" in the title, does this mean you want to exclude weekends (i.e. Saturday and Sunday) from your number of treatment days to get the final date ?

Yes abolutely

One of those that is easy to say, a little more difficult to do in AI2 !

We needed to use quotients and remainders along with getting the number of days in the first week to work this out

Tested most of the scenarios for this, they all appear to work.

I include an aia file for reuse

Enjoy :)

note: there may be a much better way to do this (couldn't find following a forum search), or even an extension to handle this scenario (I didn't look for one as was interested in working it out)

What about national holidays?

Are they workdays too?

Now there is a spanner in the works !!! :)

There is always one, isn't there :)

Happy New Year :)

I avoided the question of when the holidays come by making it 

a user-controlled list in TinyDB.

Also, I show the work days explicitly in a List Picker,

to be sure.

The data format used is customizeable in the format() procedure.

That becomes important if you want to switch to a more sortable format, like

yyyyMMdd.

See attached.

Happy New Year! :)
