Committee member Josepha Murray said they sold the sponsorship within four days of taking the idea to the community.
"We added on an extra month because people said, please, can we be involved. "There's a few on the list for next time."
She said the idea came from a Wellington school, Clyde Quay, who did a calendar each year. "It's a great way to bring the community together.
"It is quite amazing how many people have said why didn't we do this before."
Greytown Plunket president Katie Abbott said they were "so excited" about the calendar.
"It looks absolutely fabulous - we're really appreciative to Geoff and all our sponsors."
Plunket have printed 1000 calendars, which sell at $17 each or three for $45.
