bi weekly is every two weeks, semiweekly means twice a week.
Yes, but colloquially people have muddled up the meaning of biweekly so it can now mean either twice a week or every two weeks. Needs clarification.
For me, biweekly is twice per week and fortnightly is every two weeks. I've already PM'd TheSwede asking for clarification. If their plan is once every 2 weeks, I'd rather them switch to once per round.
biweekly is twice per week, bimonthly is twice per month, biyearly is twice per year
