Moon Phase Calendar



**We are sorry but our Moon Phase Calendar is presently not functioning. We know you find it useful and we will restore it as soon as we can. In the meantime please use the links below to find the Moon’s phase**

Use this calendar to follow the changing phases of the Moon.

It’s best to view the Moon through your telescope or binoculars in the first quarter of the calendar. Deep shadows outline craters and other topographical features during this time.

This calendar is indicative only and may be in error by up to one day. For accurate Moon phases, see the monthly sky charts on our blog and in the Australian Sky Guide, which also includes daily Sydney high and low tide times.
