Here is a data art calendar for 2018. We made it with p5.js and Illustrator. Our aim was to represent year as work days and holidays, for this we show all days in three possible ways: working day, weekend and holiday. The year traditionally was split into months, each in result looks like a star or spot. The most austere for Ukraine are February and November: the minimum of 8 weekends and no holidays. Moreover, this calendar is interactive: user can mark his/her own holidays with white pen and so make it more personal.
