ACALENDAR or month calendar, for any date, displays icons next to the day, icons for matching 2 other date sets, holidays, and other dates.
If someone wants the formula for Sunday as first day of the week, or other configuration, let me know.
Excel Formula:

This is how it looks properly aligned. The formula is important. The format design , colors, icons, alignment or meaning of data sets can be changed to fit anybody's needs.

This is a great one as usual. How do you get the colored calendar icon?

Thanks a lot!!! What you will always see here is due to the BB code transformation, but on your spreadsheet, you can use Conditional Formatting as you like. The icons are like any other font, so you can change or choose any color or formatting. Here is an example.

This is how it looks on spreadsheet (screen capture)

If somebody needs the calendar weekdays to start with Sun instead of Mon we have to modify the formula only on 2 places subtracting 1 (-1). Could have been done with an argument but I wanted to keep it simple.
-on the formula row that starts with xd , modify sd variable from fd-w-14 to fd-w-15
xd,EDATE(dx&"-"&mx&"-"&yx,0),fd,EOMONTH(xd,-1)+1,w,WEEKDAY(fd,3),sd,fd-w-15,sq,SEQUENCE(8,7,sd),
-on the formula row that starts with fr , modify sr variable from TEXT(SEQUENCE(,7,2) to TEXT(SEQUENCE(,7,1)
fr,CHOOSE(SEQUENCE(,7),"","",TEXT(fd,"mmm"),TEXT(fd,"yyyy"),"","",""),sr,TEXT(SEQUENCE(,7,1),"ddd"),
Here is a screen capture:
ACAL CF pic 3.jpg

Obs: You can notice that the formula updated dynamically to today's date 5-05-21 (posting date), since the formula has the first 3 arguments d,m,y ignored ( =ACALENDAR(,,,B13:B15,C13:C16) )
 
Happy New Year everyone!!
Inspired by today's Chandoo YT (5-Jan-2022), I thought ACALENDAR also deserves an update, this time with lot more functionality.
Check his variant here: FREE 2022 Calendar and Planner Template with Excel
ACALENDAR is designed not as a template, is based only on formulas/functions and 2 input tables "Cat" and "Ev", can be called on any cell, any spreadsheet, more instances at the same time.
Functionality:
- can handle any dates from past or future, any years
- we can define as many event categories as we want
- added event duration and more events/same day functionality
- bonus function, AGENDA, which can call the events table, filtering for dates or one or more events, or searching dynamically for one or more words through events description (notes)
First, I will cover the designed concepts, and, at the end, the functions.
1st concept is about expanding a sequence of dates based on duration, and building a relationship between 2 arrays, like a Data model.
2nd concept is about adding corresponding icons to the corresponding dates.
This post will be about input tables setup, names, headers, input example, icons.
