What were the ages of Pandavas & other characters during the Mahabharata war?
As per this research article of Mahabharat timeline, Yudhisthira was 91 years old at the time of Mahabharat war. And since all other pandava brothers were younger nearly by one year successively (excluding Sahadeva), there ages at the time of war would have been as below approximately:
Yudhistihra - 91 yrs, Bhima - 90 yrs, Arjuna - 89 yrs, Nakula and Sahadeva - 88 yrs
However, this other site states the age of Yudhistira as 49 years and Devavrata as 140 years. But the first site calculations seem to be more perfect than this one although that doesn't says Bhisma or Devavrata's age. I have found this site while searching today which also says the age of Bhisma was nearly 140 while dying as per his year of birth and death.
