Brisbane Queensland March / Posted 6 days ago by
28 March (Saturday) 2020 – Earth Hour – Switch off your lights from 8:30pm to 9:30pm to send a message about climate change.
Of course you don't need to stop at this one day. Use this as a trigger to think about all the lights we leave on that could be turned off every night in office buildings and homes when the room is not in use.
Normally held each year on the last Saturday in March.
