We can work out how old Xerxes was, from history books (like the Greek historian Herodotus) as well as the internal evidence in Esther. He was born in 518BC. He became King of Persia in 485BC at the age of 33. He deposed Queen Vashti in 483/482BC when he was 36 (Esther 1:3). He had a war against Greece in 480-470BC, when he was 39-49. He married Esther in 479BC (Esther 2:16), when he was 40. He killed Haman in 473BC, when he was 45 (Esther 3:7). He was assassinated in 465 BC, when he was 53.
Even with the technological advancement, Indian women still wear such intricate and delicately beautiful clothing and jewelry. They seem to really embrace femininity, instead of burying it like we seem to do in the West.
