Scroll down till you find the Central Office or Intergroup telephone number for the area that you are interested in -- and, give them a call. The most accurate meeting info can be had through the phone. Sometimes, meetings close, move, or temporarily will not be held. Often, the Intergroup or Central Office will be notified first. (Although, not always).
The websites... just like the phones... and even with meetings... are all a volunteer effort.
I used to list individual meetings here at Step12.com -- but with tens of thousands of meetings -- and thousands of changes each week -- I decided it was best to connect people with the Intergroup, Central Office or Hotline telephone numbers.... or, else... it would take thousands of hours to keep the lists up to date.
And, once a person to person connection has been made over the telephone -- often, one alkie might meet the other alkie at the meeting.
