+# Date Functions
+
+## now
+
+The current date/time. Use this in conjunction with other date functions.
+
+## date
+
+The `date` function formats a date.
+
+
+Format the date to YEAR-MONTH-DAY:
+```
+now | date "2006-01-02"
+```
+
+Date formatting in Go is a [little bit different](https://pauladamsmith.com/blog/2011/05/go_time.html).
+
+In short, take this as the base date:
+
+```
+Mon Jan 2 15:04:05 MST 2006
+```
+
+Write it in the format you want. Above, `2006-01-02` is the same date, but
+in the format we want.
+
+## dateInZone
+
+Same as `date`, but with a timezone.
+
+```
+date "2006-01-02" (now) "UTC"
+```
+
+## dateModify
+
+The `dateModify` takes a modification and a date and returns the timestamp.
+
+Subtract an hour and thirty minutes from the current time:
+
+```
+now | date_modify "-1.5h"
+```
+
+## htmlDate
+
+The `htmlDate` function formates a date for inserting into an HTML date picker
+input field.
+
+```
+now | htmlDate
+```
+
+## htmlDateInZone
+
+Same as htmlDate, but with a timezone.
+
+```
+htmlDate (now) "UTC"
+```
+
