Dates

now, dateFormat, dateParse — built on java.time.

Date/time builtins use Java’s java.time API. Available on JVM and Scala Native (which has a java.time shim) — Scala.js works too via scala-java-time if you pull it in as a dep.

Function	Arity	What
`now`	0	Current `LocalDateTime`
`dateFormat`	2	`dateFormat date pattern` — render a date with a `DateTimeFormatter` pattern
`dateParse`	2	`dateParse string pattern` — parse a string into a date

Examples

{{ now | dateFormat 'yyyy-MM-dd' }}                today
{{ .page.date | dateFormat 'MMMM d, yyyy' }}        December 7, 2025
{{ .page.date | dateFormat 'EEEE' }}                day of week

{{ d := dateParse .feed.pubDate 'EEE, dd MMM yyyy HH:mm:ss Z' }}
{{ d | dateFormat 'yyyy-MM-dd' }}                   re-format
