alrm is a quick countdown timer for your terminal. Alarms and timers are useful, but I found myself wanting to know how long I have left until an appointment or how long it is until lunch. Simply give alrm a time of day and it will tell you how long you have until then.

alrm 21       # prints the time until 9:00 pm
alrm 9:30 pm  # prints the time until 9:30 pm
alrm 9:00 -u  # counts down to 9:00 am and then exits

If the given time has already passed today, alrm will start counting down to the time that will occur tomorrow.

cd alrm
cargo install --path .
