Answer:I'm not sure to what 'Special Talk' you're referring to. Besides the regular weekly talks held held at the local Kingdom Halls weekly, there are several special circuit assemblies and district conventions where bible based topics are discussed.The locations of the assemblies and conventions are usually held at larger venues such as coliseums and amphitheaters. To determine the locations/dates of one nearest you, please contact Jehovah Witness Kingdom Hall in your area or if your in the United States, write to:Jehovah Witnesses,25 Columbia HeightsBrooklyn, NY 11201-2483.If your talking about the Memorial, where we observe Jesus ransom sacrifice, that will be held on Tuesday, March 30th. Again please contact the local Jehovah Witness congregation for location and timesHope this helps!! :-)
