Waiting between meat and dairy

Hi,

We wait after we eat meat, before we eat dairy.

The gemara mentions the need for separate meals, but it does not say how long one must wait in between. Customs to wait various times, from one hour to six hours, have developed; each family should follow its custom.

(Shulchan Aruch Yoreh Deah 89:1; Taz Yoreh Deah 89:2)

Have an easy and meaningful fast,
Mordechai
