The 42-year-old "Bang Bang" star took to Twitter to announce the release date as well as wrap on the Ashutosh Gowariker-directed project.
"Journeys that test strength of character are ones you should be most PROUD OF! Its a WRAP! #MohenjoDaro @hegdepooja," Hrithik tweeted.
The actor also shared a picture of himself holding a clap board flashing the release date with "Lagaan" filmmaker in the background.
Also starring debutant Pooja Hegde and veteran actor Kabir Bedi, the movie is an epic adventure-romance set in the ancient city of Mohenjo-daro, Sindh, Pakistan in the era of the Indus Valley civilisation that dates back to 2600 BC.
The movie marks Gowarikers second collaboration with Hrithik after 2008 film "Jodhaa Akbar".
