如何在Excel公式中添加OR函数？优先实现周四差异化执行逻辑

Hey Susan! Let's get that Thursday-specific logic sorted out for your formula.

First, let's break down your current formula to make sure we're on the same page:
=IF(WEEKDAY(E3,2)<6, "Wake up", "Sleep")
This checks if the date in E3 is a weekday (Monday to Friday, since WEEKDAY(E3,2) returns 1 for Monday up to 5 for Friday) and shows "Wake up"; for weekends, it shows "Sleep".

Now, to add a unique action for Thursday (which corresponds to WEEKDAY(E3,2)=4), you can integrate the OR function—this is especially useful if you ever need to group multiple days for the same special action later. Let's cover two practical scenarios:

Scenario 1: Only Thursday needs a unique action #

While a nested IF works perfectly here, using OR lets you leave room to add more special days down the line. Here's how to structure it:
=IF(OR(WEEKDAY(E3,2)=4), "Your Thursday Action", IF(WEEKDAY(E3,2)<6, "Wake up", "Sleep"))
(Note: Using OR with a single condition is redundant right now, but this setup makes it easy to add another day later—like OR(WEEKDAY(E3,2)=4, WEEKDAY(E3,2)=2) for Tuesday and Thursday.)

Scenario 2: Thursday + other days share the same special action #

If you already know multiple days need the same unique behavior, OR simplifies grouping those conditions. For example, if Thursday and Tuesday both require "Team Sync Day" instead of "Wake up":
=IF(OR(WEEKDAY(E3,2)=2, WEEKDAY(E3,2)=4), "Team Sync Day", IF(WEEKDAY(E3,2)<6, "Wake up", "Sleep"))

Bonus: Quick prep for holiday exceptions #

Since you mentioned wanting to build a holiday list later, here's a sneak peek at how to integrate that once you have a range of holiday dates (say, $G$2:$G$10):
=IF(ISNUMBER(MATCH(E3, $G$2:$G$10, 0)), "Holiday Rest", IF(OR(WEEKDAY(E3,2)=4), "Thursday Action", IF(WEEKDAY(E3,2)<6, "Wake up", "Sleep")))

Just replace "Your Thursday Action" with whatever specific text you want for Thursday, and adjust the holiday range to match your list!
