The leaves turn yellow to give the bulb their food for storage. If the leaves didn't yellow and wither away the bulbs would not get enough food for the Winter. Leaves turning yellow is very good for your Daylilies and always let them die back completely before removing them.
NOT A EXPERT! Just a grow worm! I never met a plant I didn’t love.✌

Daylilies are not bulbs @oneeyeluke and they do not die back unless they are dormant daylilies nor do you ever remove them for the winter. Perhaps you are thinking of lilies, lilium.

At this time of year, day lilies might get a few yellow leaves near the base of the plant. This is the older or smaller leaves dying back as the lush new leaves grow up top. Nothing to worry about.

But if the newer leaves are turning yellow, it might be a signal of a nutrient deficiency. A picture of your plant would be helpful.

Welcome! Hurray! Glad to have you! Smiling

Daylilies have roots, not bulbs. It sounds like yours are lillium. They have a very short bloom time in comparison to other perennials, and they go completely dormant long before Fall and frost, etc. Their foliage does turn yellow and "dies back" after all the blooms are spent for the season, similar to the behavior of daffodils. They remain dormant, and the bulbs increase in size and numbers, for the following season. If the foliage has sort of an architectural look to it, then they are lillium, and not daylilies.

This is an example of daylilies. The foliage is strap-like Smiling

.....and this is what daylily roots look like....

As they increase, they're called clumps, and they can be divided when the clump gets large. There are 11 divisions in this photo.

Hope this helps Smiling

The question was why do daylilies get yellow leaves?
Just the normal process of the leaves aging will cause the older leaves to turn yellow.
This year in my garden they got yellow leaves because:
I used dish detergent in with my spray and that seemed to have caused the sun to slightly burn the leaves.
Leaf streak:, something I was spraying for trying to keep my leaves from turning yellow.
The number one reason in my garden this year for the leaves turning yellow has been rust, the worst I have seen it, but it should have been expected due to the total lack of cold weather we experienced this winter.
Then there are aphids and mites, and thrips that will speed up damaged leaves turning yellow.
The drought last year caused a lot of the leaves to turn yellow and then die off (lack of water). Over doing the fertilizer can burn the plants and turn the leaves yellow.
Rot root will cause the leaves to turn yellow and die.
That is a list of just some of the reasons daylily leaves turn yellow.

Since @dyzzypyxxy answered the question, along with you, now I tip my hat to you. I tip my hat to you. I simply focused a bit more on liliums and the reason their leaves turn yellow bc @oneeyeluke mentioned bulbs in his answer, which might (or might not) confuse @Sameiwasthinkingpass (and any other new member who happens upon this thread) but at least to help @oneeyeluke understand the difference between the two. So, expanding upon Sue's explanation that there's a difference between the two, I was simply explaining more in depth on how to identify daylilies and lilium, using photos as an example, bc some may not know the difference from a short explanation without photos.

bloominholes2fill,
Sorry if you thought my post might be directed toward your reply, it was not. I saw nothing at all wrong with your further explanation. I just was not sure if oneeyeluke had used the term "bulbs' by mistake or if he was just assuming that Sameiwasthinkingpass did not know what a daylily was, even though she specifically asked about "Daylilies".
