Hormersdorf is a former municipality in the district Erzgebirgskreis, in Saxony, Germany.

Since 1 January 2013, it is part of the town Zwönitz.

In Hormersdorf a "Ziffern-Uhr" (Ziffer clock) was installed that displays the time of day in the local Erzgebirgisch dialect which uses the word "Ziffer" for units of five minute intervals.

The image of the clock at the left shows "zwee Ziffern zwee'e" in the dialect meaning 01:10 (literally "two Ziffers of the second hour", a Ziffer being five minutes, the second hour being 01:00 to 02:00 or 13:00 to 14:00 in daytime).
