I understand "at" is used with weekends in British English.<br/><br/>How do they something like,<br/><br/>"I plan to go there "on/at" one weekend next month" .<br/><br/>Is the sentence right? Should "one" be replaced by "a"?<br/><br/>Do the British say, "I plan to go there at a weekend next month" ?<br/><br/>Thanks,<br/>Prasanna
