Online alarm clock for 2:39 am
As you hand the pre-dawn milking over to another worker in Waikato, set the alarm for 2:39 am so the changeover happens at the intended moment. That leaves a useful stretch before 3:00 am for passing on notes about the herd, the shed, or any jobs already under way.
During a milking handover, the alarm page may be left behind another browser window while records or messages are checked. Keep its sound enabled and return to it before relying on the alert, since browsers can limit activity on a page running in the background. If the computer goes to sleep or the browser session ends, the milking changeover will receive no alarm, so the incoming worker should have a separate fallback.
Once the Waikato shed is in someone else’s hands at 2:39 am, leave a clear buffer before the next job rather than filling every minute. Note what must happen later that morning, allow time to clean up and travel, and set a second reminder only if it supports that next task. In the darkness before dawn, a small margin also makes it easier to check that keys, wet-weather gear, and anything needed for the day have gone with the right person.
