72,500 calendars were printed by a TD in the run-up to Christmas using in-house facilities.
Tipperary deputy Séamus Healy ordered the printing of the double-sided A4 calendars for constituents, costing a total €2,004.55.
The quantities printed far exceeded the numbers ordered by any other TD or senator in the run up to Christmas, according to figures released to the Oireachtas under the Freedom of Information Act.
Mr Healy defended the large order, saying the calendars were not specifically for Christmas.
"There is no reference to Christmas or the New Year on the calendars", he said. "They are in no way a replacement or substitute for Christmas cards. To confuse my calendars with Christmas cards is very mis-leading.
"They [the calendars] provide contacts details for local hospitals, health centres, social welfare services, emergency services, garda services etc. Constituents need to have this information at hand so that they can quickly access the services to which they are entitled.
Mr Healy added that distribution of the calendars would not take place until the New Year.
"My record as a public representative at local and national level is one of opposing unnecessary levels of public expenditure [...] I have never participated in 'junkets'."
In total, 16 TDs used the in-house printing facilities to produce cards and calendars. The overall cost in 2016 was just short of €5,500.
Other TDs who printed calendars included Michael Healy-Rae (10,000) and his brother Danny (8,500). Taoiseach Enda Kenny ordered 500 calendars.
