How to use the 2023 Calendar Workbook?
The calendar & planner file has 4 tabs.
- Calendar tab: See the 12-month calendar view + upcoming activities in this page. It also highlights any holidays, weekends and planned activities on the calendar in a different color.
- Any month tab: This page lets you see the calendar for any specific month in a detailed view. You can change the month from cell C3 and the calendar updates automatically. The calendar shows date, any activities planned in a neat grid view.
- Planner tab: Use this tab to set up your activities. Whatever items you list here will automatically show up on the calendar & any month tabs.
- Customizations tab: Do you want to change the way your week begins? Need to add some holidays or change the icons? Use the customizations tab.
How is this calendar made?
The calendar workbook has two main components.
- Calendar
- Planner
Calendar Generation

To generate the calendar, I am using the dynamic array functionality of Excel 2023. We can use the SEQUENCE function to create all the dates in any given year.
For example, =SEQUENCE(365,,DATE(2023,1,1)) generates all the 365 dates in the year 2023.
I then used the same logic to generate monthly calendars for all the 12 months and adjusted them based on the week start option.
Once the monthly calendars are generated, then I highlighted the weekends, holidays and activities using conditional formatting.
Activity Planner

You can set up any number of activities in the planner table. I am then using FILTER function to filter out the activities for a given day and show them next to the calendar date.
Also, if “highlight activities” is enabled, then I am highlighting the calendar cells in a different color.
In the 12-month calendar view, I am showing upcoming 10 activities using FILTER function too.

One Response to “SQL vs. Power Query – The Ultimate Comparison”
Enjoyed your SQL / Power Query podcast (A LOT). I've used SQL a little longer than Chandoo. Power Query not so much.
Today I still use SQL & VBA for my "go to" applications. While I don't pull billions of rows, I do pull millions. I agree with Chandoo about Power Query (PQ) lack of performance. I've tried to benchmark PQ to SQL and I find that a well written SQL will work much faster. Like mentioned in the podcast, my similar conclusion is that SQL is doing the filtering on the server while PQ is pulling data into the local computer and then filtering the data. I've heard about PQ query folding but I still prefer SQL.
My typical excel application will use SQL to pull data from an Enterprise DB. I load data into Structured Tables and/or Excel Power Pivot (especially if there's lot of data).
I like to have a Control Worksheet to enter parameters, display error messages and have user buttons to execute VBA. I use VBA to build/edit parameters used in the SQL. Sometimes I use parameter-based SQL. Sometimes I create a custom SQL String in a hidden worksheet that I then pull into VBA code (these may build a string of comma separated values that's used with a SQL include). Another SQL trick I like to do is tag my data with a YY-MM, YY-QTR, or YY-Week field constructed form a Transaction Date.
In an application, I like to create a dashboard(s) that may contain hyperlinks that allow the end-user to drill into data. Sometimes the hyperlink will point to worksheet and sometimes to a supporting workbook. In some cases, I use a double click VBA Macro that will pull additional data and direct the user to a supplemental worksheet or pivot table.
In recent years I like Dynamic Formulas & Lambda Functions. I find this preferable to pivot tales and slicers. I like to use a Lambda in conjunction with a cube formula to pull data from a power pivot data model. I.E. a Lambda using a cube formula to aggregate Accounting Data by a general ledger account and financial period. Rather than present info in a power pivot table, you can use this combination to easily build financial reports in a format that's familiar to Accounting Professionals.
One thing that PQ does very well is consolidating data from separate files. In the old days this was always a pain.
I've found that using SQL can be very trying (even for someone with experience). It's largely an iterative process. Start simple then use Xlookup (old days Match/Index). Once you get the relationships correct you can then use SQL joins to construct a well behaved SQL statement.
Most professional enterprise systems offer a schema that's very valuable for constructing SQL statements. For any given enterprise system there's often a community of users that will share SQL. I.E. MS Great Plains was a great source (but I haven't used them in years).
Hope this long reply has value - keep up the good work.
