LSDayOfWeek()

Returns the day of the week the date represents in locale format.

LSDayOfWeek( date=datetime, locale=locale, timezone=timezone );

Returns: Number

Argument Description
date
datetime, required

date object; for example, now()
locale
locale, optional

Locale to use instead of the locale of the page when processing the function
timezone
timezone, optional

A datetime object is independent of a specific timezone; it is only an offset in milliseconds from 1970-1-1 00.00:00 UTC (Coordinated Universal Time).

The timezone only comes into play when you need specific information like hours in a day, minutes in a hour or which day it is as these calculations depend on the timezone.

A timezone must be specified in order to translate the date object to something else. If you do not provide the timezone in the function call, it will default to the timezone specified in the Lucee Administrator (Settings/Regional), or the timezone specified for the current request using the function setTimezone().

You can find a list of all available timezones in the Lucee administrator (Settings/Regional). Some examples of valid timezones include:

  • AGT (for time in Argentina)
  • Europe/Zurich (for time in Zurich/Switzerland)
  • HST (Hawaiian Standard Time in the USA)
  • JVM (JVM / Server Default Timezone)

Examples

dump(lsdayofweek(now()));
