According to sources, Modi announced the date in his response to the summon issued to him by the SIT, which is probing the 2002 riots.
SIT wants Modi to depose in connection with a complaint of Zakia Jaffry, widow of former Congress MP Eshan Jaffery who was killed in Gulburg society riot case of 2002 along with 69 others.
Jaffry had alleged the indirect involvement of Gujarat Chief Minister and 61 others in the massacre.
Jaffry's charges against Modi state that, "As head of the state, he was responsible for fundamental rights, right to life and property of all citizens regardless of caste, community or gender."
The Supreme Court of India had ordered the SIT to look into the allegations.
