How to find week of the year for the date value?

[prabhu Mahendran <pr...@gmail.com>]

My Flow having attribute '05-05-2015'.And i need to find week of the date
in NiFi.

For example:

if date is 05 then it is belongs to 1st week of the year.

I shouldn't use Script/Program for find out week.

i need to find out that using NiFi Expression language only.

Can anyone suggest way to do that?

Prabhu,

You can use the "toDate" function to convert that string into a Date and then use
the "format" function to convert that date into what you want using the patterns defined
for SimpleDateFormat. You can see what those patterns/symbols mean and examples
at [1]. I hope this helps.

Thanks
-Mark
