The truces come more than a year into fierce daily battles in and around several areas of the city that have led to rebels and President Bashar al-Assad's forces deciding to compromise, with neither side able to claim victory.
In addition to Babbila, deals have been struck for local ceasefires in Qudsaya, Moadamiyet al-Sham, Barzeh, Beit Sahem, Yalda and Yarmuk Palestinian refugee camp.
The accords are negotiated by public personalities from disputed areas, including businessmen and former ministers.
A new agreement is reported to be in the offing for Harasta, a rebel bastion northeast of Damascus, and talks over Daraya southwest of the capital are also taking place.
