1277. The rainbow calendar

    This is a present from Pepe Chapuzas. It's a calendar for several years, since 2014 until 2030, although it can be extended. 

    Dear Teacher:
    If I want to know what day of the week will be October 13th 2027? First, I look for the color that relates October (X) with 2027 (27): it's green! Then, I look for the day of the week that is related with the 13th (13) by the color green: it's Wednesday (mi). (Spanish miércoles.)

    Leap years appear twice: in one black cell and in one white cell. The black one are reserved for January and February, so, February 6th 2024 will be Tuesday (ma). (Spanish martes.)

 Days of the week in Spanish:

lunes

martes

miércoles

jueves

viernes

sábado

domingo
