There have been around eight ice ages in the last million years, with each ice age lasting for tens of thousands of years. These ice ages were characterized by the expansion of glaciers and ice sheets over large portions of the Earth's surface, resulting in cooler temperatures and lower sea levels.

How many years did the ice age last?
Ice ages last for some tens of millions of years with intervals of about 150 million years between them. The term is used more loosely to identify the last time that ice sheets covered much of Europe and North America.
How many ice ages have there been in the past 400 thousand years?
Just the one, the same one we live in now which started about 2.6 million years ago. As far as glaciations are concerned there have been at least 3, possibly 4, in the last 400,000 years.
In the last 200000 years how many ice ages have there been?
There have been about 8-10 major ice ages in the past 800,000 years, occurring approximately every 100,000 years. These ice ages are characterized by periods of lower global temperatures and expanding ice sheets.
How many years are there from ice age to ice age?
There have been multiple ice ages throughout Earth's history, with each one lasting millions of years. The time between ice ages can vary greatly, from hundreds of millions to billions of years, depending on geological and climatic factors.
How many glacial periods have there been for the last two million years?
There have been multiple glacial periods during the last two million years, with Earth experiencing numerous advances and retreats of ice sheets. This period is commonly referred to as the Quaternary Ice Age, characterized by alternating cold glacials and warmer interglacial periods.
How many years did the middle ages last?
It was a 1,000 years long.
How many years did the ice age last?
Ice ages last for some tens of millions of years with intervals of about 150 million years between them. The term is used more loosely to identify the last time that ice sheets covered much of Europe and North America.
How many glacial periods have there been during the last two million years?
There have been multiple glacial periods, known as ice ages, during the last two million years. These ice ages are characterized by intervals of cold climate when ice sheets covered much of the Earth's surface. The exact number of glacial periods can vary depending on the scientific definition used.

About 20,000 years ago. I read it off of Wikipedia. There have been many ice ages over the past 2.4 billion years. The present ice age started about 2.6 million years ago although there have been many warm periods,(interglacials), during that time, we are in one now.
