Calendar Notes

A normal Harptos year has 365 days: twelve 30-day months and five intercalary holidays. Shieldmeet follows Midsummer once every four years, producing a 366-day year.

Traditional astronomical markers are shown on Ches 19, Kythorn 20, Eleint 21, and Nightal 20. The Sword Coast Adventurer's Guide records a temporary shift of the seasons in 1488 DR, when the spring equinox fell on Greengrass.

Weather descriptions use Waterdeep as a Sword Coast reference. They are qualitative because Faerun spans many different climates.
