Watches that display not only the time but also the date and calendar are convenient.
However, some people may have experienced that the display was out of alignment when they checked their watch one day.
Therefore, in this article, we will explain the reasons why the date/calendar is misaligned and how to adjust it.
If you are looking for a way to restore the date/calendar deviation of your watch, please refer to it.

4 reasons why the date/calendar on your watch is out of sync
The original role of a wristwatch is to tell the time, and the date and calendar functions are secondary.
As a result, the display functions of many watches are not universal and are often misaligned.
Below are three reasons why the date/calendar may be misaligned.
operates on a 31-day cycle
The first possible cause is that the display function operates on a 31-day cycle.
Most watches reset on a 31-day cycle in any month.
Therefore, even if there is no 31st day in February, April, June, September, and November, the 31st day (and the 29th and 30th in the case of February) ignores the original monthly cycle. It is displayed.
In this case, it cannot be helped due to the specifications of the display function, so it is necessary to adjust each month at the change of these months.
I made an adjustment during a time when it should not be adjusted
The second possible cause is that the adjustment was made during a time when it should not be adjusted.
Some watches do not allow the time and date to be adjusted between 20:00 and 4:00.
Due to the structure of such watches, the display function may be damaged if adjusted during this time period.
Date change prohibition period for mechanical watches
In this article, we explain in detail why you should not change the date during the date change prohibited period and what will happen if you change it. Please take a look.
the inside of the watch is broken
The third possible cause is that the inside of the watch is broken.
A watch is a precision instrument made up of many small parts.
Therefore, the internal parts are easily broken by giving a shock, and normal operation is not performed.
In particular, if the gear-like parts that make up the mechanism of the display function break, misalignment will occur.
Lack of oil in parts
A final possible cause is lack of oil in the parts.
Inside the watch, oil is applied to keep the parts intertwined smoothly.
However, when there is less oil in the parts, friction will occur between the parts, leading to failure of the parts.
If that happens, the display function of the date and calendar will also be affected, and the display will be misaligned.
How to adjust the date/calendar on your watch
Once you understand why the date/calendar on your watch is misaligned, all you have to do is adjust it.
However, you may or may not be able to make adjustments yourself.
Below are three ways to adjust it.
Rotate the time setting crown
The first way to adjust the date/calendar on your watch is to rotate the time setting crown.
Most wristwatches are equipped with a rotating projection called a crown that allows you to adjust the time, date and calendar.
The crown is divided into a mode where you can change the time and a mode where you can change the date and calendar.
By rotating the time setting crown until the date changes, it is possible to adjust the desired date.
Rotate the date setting crown
The second way to adjust the date/calendar on your watch is to rotate the date setting crown.
By rotating the date setting crown in the same way as rotating the time setting crown, it is possible to adjust the desired position.
Unlike the time setting crown, the amount of rotation is small, so it can be easily adjusted.
However, some crowns for setting the date can only advance the numbers forward, so if the numbers are advanced too far, you will need to turn the crown one more rotation.
In that case, be careful not to rotate too much.
send in for repair
If the internal parts or crown of your watch are broken, repairs may be required to adjust the date/calendar.
Watches are difficult to repair on your own, so it's best to send them in for repairs instead of trying to fix them.
Main causes of wristwatch failureSince watches are precision instruments, there are various symptoms of failure. If you want to use your watch for as long as possible, or if you have symptoms like a breakdown and feel uneasy, please refer to it.
Typical examples of wristwatch failure
- the needle stops
- [Quartz type only] Does not work even after replacing the battery
- Time lags or advances
- Calendar date display does not work
- The glass of the watch fogs up and condensation occurs
- Shaking the watch makes a sound
- [Mechanical type only] Tight screws

If you feel something is wrong with the date/calendar on your watch, consult a specialist!
What did you think.
Since the date/calendar display function of the watch is secondary, it is not uncommon for it to be off.
Many deviations can be eliminated by rotating the crown.
However, depending on the type of watch, adjusting it between 20:00 and 4:00 may lead to malfunction, so be careful.
