Question

I’m working on a django template, and I want to format a date with the following format ‘YYDDD’ (sometimes known as julian date format) where:

• YY is the last 2 digits of the year
• DDD is the day of the year with 3 digit format

I tried to achive this with the date filter:

{{ value|date:"yz" }}

but “z” doesn’t keep the output with 3 digits, it uses the minimum possible amount. If the day number is 3 (3rd January) it will print 3 istead 003.

For example, for the date 7th February of 2012 i would expect 12038 but instead I get 1238 (no zero padding).

How can I get this right?

You can write your django custom filter or use jcroft’s snippet:

{{ value|date:"y" }}{{ value|date:"z"|leading_zeros:"3" }}
