Summer Vs. Winter Photo

In Chinese astronomy, summer starts on or around 5 May, with the jiéqì (solar term) known as lìxià (立夏), i.e. "establishment of summer", and it ends on or around 6 August.
In southern and southeast Asia, where the monsoon occurs, summer is more generally defined as lasting from March to May/early June, their warmest time of the year, ending with the onset of the monsoon rains.
Because the temperature lag is shorter in the oceanic temperate southern hemisphere most countries in this region, especially Australia and New Zealand, use the meteorological definition with summer starting on December 1 and ending on the last day of February.
