Is there any way to do date arithmetic

[skdutta-ga]

Say I want to subtract a few days to the date, in liquid we can do something like:

my_date | date: "%s" | minus : 604800

is there an equivalent or workaround in dotliquid?

[laedit]

Please, when you report a bug add the error message.
In this case, I think it's because you try to subtract a number to a date.
A pull request would be welcome 😄

Pathoschild.NaturalTimeParser has a plugin for DotLiquid that can do this.

So for example {{ 'today' | as_date | date_offset:'30 days' | date:'yyyy-MM-dd' }}.
