No school holiday period falls within May in any state, since Term 1 ends in April and Term 2 runs through the whole of May 2028 without a break. School assessments and the usual mid-term rhythm of parent-teacher meetings continue uninterrupted across every state and territory through to the mid-year school holidays that begin the following July. Mother's Day falls on the second Sunday of May every year.
With no public holiday in May outside Queensland and the Northern Territory, leave planning around May 2028 depends entirely on annual leave taken independently of a long weekend. Many workers use this quieter stretch of the year to take leave before the King's Birthday long weekend arrives in June and the ski season opens further south. Whale migration season runs along much of the coastline throughout May.
The shift from May into June brings the start of winter on 1 June and the King's Birthday long weekend that most states observe on the second Monday of the month. May 2028 hands over an ordinary working month to one shaped by both a seasonal change and the financial year's close on 30 June. May sits in the second calendar quarter of 2028, which runs from April to June.
