Your best time to post is the hour window where your own posts beat your own median, and you can find it with a four-week test, not a generic chart. Fix the hour, change nothing else, and compare. That is the whole method, and it works because it uses your audience instead of an average of everyone's.
TLDR: Skip the universal "best time" charts. Pick two candidate windows, post in each for two weeks with the same content mix, and compare reach against your own median. In Mydrop's data, the one proven loser is midnight to 6 am local time, and the weekday barely matters.
Mydrop data, September 2026: across 7,945 posts on 336 accounts connected to Mydrop, measured in each account's local time, the weekday made almost no difference: every day sat within 2% of the account's median. The one clear loser was posting between midnight and 6 am, 17% below the median across platforms and 36% below on Instagram. Method and full tables in the Mydrop social media benchmarks.
Rule out the one time that is already proven bad
Before you test anything, stop doing the thing that costs you reach. In the data above, posts between midnight and 6 am in the account's local time ran 17% below the median across platforms, and 36% below on Instagram.
That makes the first fix free. If a scheduler is publishing at 2 am because your server or tool is set to another time zone, move those posts into daytime hours today. Check the time zone setting in your scheduling tool before you check anything else.
Skip the weekday, test the hour
Most "best day to post" advice is noise. In the same dataset every weekday sat within 2% of the account's median. A Tuesday is not meaningfully better than a Saturday.
The hour is where the differences hide, so that is what you test. Your audience's daily rhythm depends on who they are: shift workers, students and parents are online at very different hours.
Choose two windows from three quick clues
You do not need history to pick candidates. Use these sources, in this order:
- Your platform's audience insights. Most show when followers are active. Take the two busiest stretches.
- Your audience's routine. A cafe has a morning commute window. A B2B software brand has a mid-morning desk window.
- Your best past posts. Sort the last 30 posts by reach and note the hour of the top five.
Write down two windows, such as 8 to 9 am and 6 to 7 pm, in the audience's local time, not yours.
Run the four-week test
The test needs discipline more than data.
| Week | What you do | What stays fixed |
|---|---|---|
| 1 and 2 | Post only in window A | Same formats, same topics, same frequency |
| 3 and 4 | Post only in window B | Same formats, same topics, same frequency |
| End of week 4 | Compare average reach and engagement per post | Use your own median as the baseline |
Two rules keep the result honest. First, change only the hour. If you also change the format in week 3, you learn nothing. Second, post at your normal frequency, so each window gets at least six to eight posts.
If the windows land within about 5% of each other, you have learned something useful: timing is not your lever. Spend your effort on the content itself, and keep the window that is easiest to schedule.
Read the result against your own median
Compare each post to the median of the whole test period, not to a benchmark from another account. A post at 1.15 times your median in window A and 0.95 in window B is a real signal. A gap of two or three points is noise.
For context on what a normal range looks like, Mydrop's benchmarks show an Instagram median engagement rate of 3.1% in the September 2026 data, with the middle half of posts between 1.1% and 6.7%. A wide spread means one post can mislead you, which is why you measure the average of several.
Handle several brands without a spreadsheet per brand
The test is simple for one account and heavy for ten. Every brand needs its own windows, in its own audience's time zone.
Mydrop's calendar lets you save the winning hour as a recurring slot per brand, and Performances shows each post against that account's own median, so you can read a test result in a minute. For the time zone problem across regions, see our guide to aligning posting times across time zones.

Start the test this Monday
Today, pick two windows and write them at the top of your calendar. Schedule the next two weeks of posts into window A only. In two weeks, switch to window B, and on day 28 compare the two averages.
