Do i have to include the year on wedding invitation?

I think you would be fielding a lot of inquiries if you left it off.

I've never seen an invite without the year. You should probably include it.

Definitely need the year.

Ha oops dont think mine has the year. But also its only 40 people and they all know even though invites arent out yet. All close friends and family thankfully

Then again it would be weird to send an invite over a year in advance

I would include the year

Traditionally it isn't necessary although commonly done. Before seeing the nonsense that shows up here from time to time, I never would have thought someone would send an invitation more than a year in advance. Now however, nothing surprises me. Include the year to avoid any confusion someone might have because of something someone else might have pulled

Include the year

I don't think so, unless you send it more than a year early. But everyone will assume it's the calendar year you send it.

If nothing else write 2018. It's less formal but depending on your style of invite that might not be a terrible thing.

Yes, for sure include the year!
