The sentence is

Please note that only candidates who actually pass the tests will receive a notification by email later on the day.

I would like to ask that "later on the day" is when? Is that specified like the next day?

    At a later time of the day.

  • Later is a general word, not specifying a time. Later in the day means before the end of the same day. But it is not a guarantee. Commented Feb 13, 2020 at 21:22
  • To be clearer it should be "later on the same day" Commented Feb 13, 2020 at 21:22
  • 3
    Or: .....later on in the day.

    Or later on that day or later that day or any of a number of things. It could be any of those or the above, but it's perfectly acceptable as later on the day where later on the day of the test is logical but omitted.

"Later on the day" is non-idiomatic in my opinion. I would assume they meant later the same day, but I would phrase it either "later in the day" or "later on in the day".

    Yes. I read it as an error. Possibly a typo intended to be “later in”

    I agree. It could be "later on that day" too Commented Feb 14, 2020 at 8:05
  • "Later that day", the on is unnecessary.

  • Maybe also later on that day. Commented Feb 14, 2020 at 17:43
  • "On the day" is often used when referring to a particular date in the future.

I cannot be sure about this but I believe that "on the day" is correct when used in respect of a date that has been referenced before the phrase is used. The referenced date could be the current date, in the past or even in the future.

Like I said, not sure - just my tuppence ha'penny's worth!

"Later on the day" is not very common and doesn't sound idiomatic to me.

Longman Dictionary only lists "later in the day":

later in the day/week/year
The dentist could fit you in later in the week.

Google Ngrams has the following result:

enter image description here

As you see, "later on the day" is almost non-existent. In fact, upon further examination, you can see that the majority of the examples have nothing to do with our case, e.g. "Later, on the day of the battle..."

Google search results seem to show a similar trend:

"do it later in the day": 1,400,000 search results
"do it later on the day": 2 search results

"announce it later in the day": 14,100 search results
"announce it later in the day": 1 search results

"by email later in the day": 6,630 search results
"by email later on the day": 4 search results, (one of which is this very page)

However, the picture somewhat changes if we search for the following:

"announced later in the day": 213,000 search results
"announced later on the day": 42,900 search results

Here "announced later on the day" is doing much better than before constituting around 17% of the results. I had a quick look at the results and here is what I have - tentatively - observed:

There are some search results of the type:

"will be announced later. On the day of the launch am I going to".

But I think the majority of the results are of the following two types:

"Winners will be announced later on the day of event." "with the winners of the President's Prize announced later on the day."

Based on the above, I tend to agree with KillingTime, Robusto, Kevin, StephenR, KeithLoughnane, among others.

To sum-up, I think "later in the day" is the much more common/idiomatic form, but some people seem to use "later on the day" as a sort of short form for "later in the day on a specific day". This is more common with announcing results, winners, etc but perhaps with some other verbs or situations that I have not considered.


Later on the day is a correct phrase which is used to express something is happened, done or will be done after something else on that same day.
