The Indian team, under new head coach Gautam Gambhir, will begin the series with the T20Is at Pallekele on July 26, 27, and 29, before moving to Colombo for the ODI leg.
The one-dayers will be played on August 1, 4, and 7.
The Indian squad for the tour has not yet been announced, but senior players like Virat Kohli and Rohit Sharma are expected to be rested, according to a PTI report.
Hardik Pandya is expected to lead the T20I side, while KL Rahul could be named as the ODI skipper.
Gambhir, who recently replaced Rahul Dravid as head coach, will be at the helm during the tour. Dravid, who led India to their second T20 World Cup title in the Americas, has handed over the reins to Gambhir.
Sri Lanka will also feature a new coach as Sanath Jayasuriya takes over from Chris Silverwood.
In addition to the coaching changes, Sri Lanka will have a new captain following Wanindu Hasaranga’s resignation on Thursday.
The tour marks India’s first white-ball bilateral series to Sri Lanka since 2021, during which Dravid served as stand-in coach and Shikhar Dhawan led a second-string side, resulting in victories for India in both T20I and ODI series.
