kalarm
A pop-up alarm can show either a simple text message, or the contents of a text or image file. It can optionally be spoken, or play a sound file. You can choose its appearance, and set reminders. Among KAlarm's other facilities, you can set up templates to allow KAlarm to be used as a 'tea timer'.

I've been using the program for many years (since version 2-10.12-ak)! At LM 19.2 I had problems with the time zones (mentioned below), but thanks to stepnjump advice (thank you!) I fixed them! Everything works fine! You can set your alarms in many ways... A fantastic application!
It's an AMAZING app! However, it is built for KDE but it's possible to have it work great in Gnome also!. Tested in LM 18.3 (cinnamon). Wasn't so lucky under LM 19.x version though. If you get the " The KDE time zone is not available: check that ktimezoned is installed", please install all the akonadi components + korganizer. Reboot then open kAlarm. Still not working. Finally install plasma-workspace then reboot. Works flawlessly! Tried in XFCE: No go! Nothing compares to this one that I know of. The programmer David is VERY helpful...
Does not work Mint 18 XFCE, missing timezone fixed on Kmail and other K-stuff.
I find it very good. main drawback being that you have to find a sound file to use. Be nice if it came with a few like other alarm clocks do.
If you are a LMDE2 user, launch the terminal, write kalarm, press Enter and it will work
Simple. Gets the job done. Exactly the features I need. I just wish it didn't require so many KDE libraries to install in Cinnamon.
Супер! Очень мне нравится эта напоминалка! Простая в настройке с богатыми возможностями
best desktop alarm app I've come across. lots of features to run message or audio alerts when you want. Even run commands like a poor man's cron (i think)
