nthClock is a free, open source desktop alarm clock I wrote many years ago. The design is considerably outdated, but I no longer work with Delphi, so there will be no further development.


The current and last version is 3.0.0, which includes snooze alarms and numerous usability improvements. See the nthClock release notes for a list of changes.

nthClock is compatible with Windows 95, NT, 98, Me, 2000, and XP. Vista and Windows 7 are not supported.


To install nthClock, download the nthClock 3.0.0 install program (3.8 MB), unzip it, double-click 'Setup.exe', and follow the instructions. Be sure to check 'Yes, Launch the program file' when the 'Setup Complete' form is displayed.

The application was developed with Delphi 5. The nthClock 3.0.0 source files (60 KB) are not needed to use the program.
