Loendë

Loendë was Midsummer's day, the Mid-year's Day of Kings' and Stewards' Reckoning.
In the old Numenorean Calendar of Kings' Reckoning, there were three such extra days belonging to no particular month, and five in later systems of the Stewards'. It was again revised in the Fourth Age so the year began in spring rather than mid-winter, causing Loendë to fall between the months equivalent to our September and October.
