Counting The Omer?
If you're counting the Omer (the days between Pesach and Shavuot), take a look at Ritualwell's Omer kavannot,   One for each of the 49 days. I'm represented, on days 17 and 26.

There are a lot of explanations for the count, but I like it as a mindfulness exercise, both for the kabbalistic exploration  of each day and also as an awareness of time.
