Is it possible to do date comparisons against the current date in a freemarker template without passing the current date into the template?
回答1:
From FreeMarker 2.3.17 on you can use the new special variable .now:
[#assign foo = .now > yesterday?datetime]

In case someone else has this issue.
I was comparing 2 dates
[#assign .now?date lte today?date]
(they both were 10/10/2019)
but for some reason it was false even though it was equal, so what I had to do was
[#assign .now?string["dd/MM/yyyy"]?date lte today?date]

Better way to compare two dates in freemarker is to find the difference between two dates.
<#assign difference = (custom_date?long / 86400000)?round - (.now?long / 86400000)?round />
If the difference is greater than 0, it's a future date, if it equal it is same date, if it less than, it is previous date

NO
Freemarker is a templating library, there isn't a today variable.
But you can pass a new Date() Java Object to the template.
