General elections are on even years.
Municipal elections are on odd years.
Maybe true for some cities but the towns in my area elect council members annually, 2 year terms for each member but staggered. School board works the same. TXBubba is asking about school board. Not sure where she lives but we definitely vote for school board members this year and the nearby towns vote for their officials.
Thank you all for the voter information! Lots of good sources. I am passing along and I have been reminded of them for myself.
