WPS Spreadsheet: Create a Dynamic Calendar with Color-Coded Events

Steven Parker Nov 12, 2026 868 views

Question details

The user needs to create a monthly calendar that automatically displays events from an event table and uses different colors for each event category.

Product: WPS Spreadsheet
Device & OS: not provided
Scenario: An event table contains dates, event titles, and categories. The user wants a calendar that updates by month and visually distinguishes categories such as meetings, holidays, or deadlines.
Observed behavior: The calendar needs to show multiple matching events beneath each date and apply category-based formatting without combining all events into one cell.

Before you start

Prepare an event table with separate columns for the event date, event title, and category. Confirm that the date column contains real spreadsheet dates rather than text, and decide how many event rows each calendar date should display.

Solution 1Recommended

Build the calendar with FILTER and category-based conditional formatting

Use this approach when your WPS Spreadsheet version supports dynamic array formulas and you want the calendar to update automatically as events change.

Reserve several worksheet rows beneath each calendar date so multiple events can spill into separate cells. Keeping each event title and category in its own cell makes conditional formatting more reliable than combining all events with TEXTJOIN.

Create the event table

On a separate worksheet, create columns named Date, Event, and Category. Enter one event per row, then select the table range and use Home > Format as Table if you want the source range to expand more easily.

Add a month selector

On the calendar sheet, enter the first day of the target month in a selector cell such as B1. Use real date values and format B1 with Home > Number Format > Date or a custom month-and-year format.

Generate the calendar dates

Create the date cells for the selected month and link them to B1. For example, the first date can use =B1-WEEKDAY(B1,1)+1, and the following date cells can add 1 to the previous date. Format the date cells as day numbers if desired.

Spill matching event titles

In the first event row beneath a calendar date, enter a FILTER formula such as =FILTER($B$2:$B$100,$A$2:$A$100=D5,"") where column A contains dates, column B contains event titles, and D5 is the calendar date. Copy the formula to the event area for each date cell.

Apply category rules

Select the calendar event range, open Home > Conditional Formatting > New Rule, and create one formula rule per category. For example, if the category is in the adjacent column C, use =$C5="Meeting" for the Meeting color, then create similar rules for other categories.

Keep event data separate: Use one cell for each event title and one corresponding cell for its category. This allows each conditional-formatting rule to evaluate the category directly and keeps the calendar readable when several events share a date.

Create and format a live event calendar in WPS Spreadsheet

WPS Spreadsheet can organize your event table, spill matching events into calendar cells with FILTER, and color each event category through conditional formatting. The familiar spreadsheet interface also makes it easy to save and share the finished calendar in Excel-compatible formats.

1. Prepare the source data: Open WPS Spreadsheet and create Date, Event, and Category columns, with one event on each row.
2. Create the calendar layout: Add a month selector and date grid, then reserve multiple rows under each date for event results.
3. Display matching events: Use the Formulas tab or a calendar event cell to enter a FILTER formula that returns event titles matching the date.
4. Color the categories: Select the event range and choose Home > Conditional Formatting > New Rule to add a formula rule for each category.

Frequently Asked Questions

Why should each event use a separate cell instead of TEXTJOIN?

Separate cells let FILTER return multiple event titles as a spill range and allow conditional formatting to evaluate the category for each event. TEXTJOIN combines several events into one text value, which makes category-based formatting difficult.

How can I show more than one event under a calendar date?

Insert or reserve enough worksheet rows beneath each date for the maximum expected number of events. The FILTER result will spill into those cells when multiple source rows match the date.

What FILTER formula displays events for a specific calendar date?

If dates are in A2:A100, event titles are in B2:B100, and the calendar date is in D5, use =FILTER($B$2:$B$100,$A$2:$A$100=D5,""). Replace the ranges and date-cell reference with the locations in your workbook.

How do I create a color rule for one event category?

Select the calendar event range, choose Home > Conditional Formatting > New Rule, select a formula-based rule, and enter a condition such as =$C5="Meeting" when the category for the first selected row is in column C. Set the fill color and repeat the process for other categories.

What should I check if FILTER returns no events?

Verify that the source dates are real date values, not text, and that the calendar date and source date include the same date. If source cells contain times, compare using INT, such as =FILTER($B$2:$B$100,INT($A$2:$A$100)=D5,"").
