How can we help?

I apologise if this has been asked before. I have looked. There is quite a lot of talk about getting multiple calendars from one gmail account - but I have a gmail for work and a gmail for home. It would be great to combine the two calendars, or have two instances of gcal: running next to each other - but if I do that, the second one seems to overwrite the first. Is there any way of doing this.

Thanks!
