Church Timings : Why ?

Many a time we miss mass or are delayed ( which to some is as good as missing mass) for mass since we do not know the times of the mass services.

Maybe because we just don;t know , are not sure or even if we are in a new neighbourhood visiting, just moved or passing through..

I would like to compile a list of all the churches and their timings and various services that they offer.

Any help is welcome !
