A quick and easy how to article on setting your mechanical clock for daylight savings.

What is the real reason for daylight savings?

Answer: Exciting news is we are about to "Spring Ahead" on Sunday, March 13. When we do this, clocks change to one hour ahead of time, hence "spring ahead". Surprisingly, humans have been setting the mechanical clock for daylight savings since the beginning of civilization. Our ancient ancestors would adjust their schedules and patterns to make sure they were able to maximize the time they could spend in the sun. Fast forward to 1784 to Benjamin Franklin publishing an article in France arguing that if could adjust the work day one could save on candle purchases. This became the legislative argument for daylight savings. As years went on, this would morph into an even more prevalent argument when WWII began. In the beginning, official laws for daylight savings were to help redirect resources to the wars.

How do I adjust my clock for 'Spring Ahead'?

Answer: For any clock movement-Advance the minute hand by hand, letting it chime and or strike as you go, slowly going around one hour. If the clock is a quarterly chime unit and the person doing the advancing went too fast, it may confuse the chimes. That is if they did not let it chime fully before moving to the next quarter, the chimes may be incorrect. However the chimes will only be wrong for an hour and then it will be fine again.

How do I adjust my clock for 'Fall Back'?

Answer: Falling back for setting the mechanical clock for daylight savings has more explaining to do as it is not the same on all clocks. For example there are some chiming battery quartz clock movements that cannot go backward.

Setting time only battery movements

For all time only units, all you need to do is to point the hour hand to the prior hour. This goes for all battery units or mechanical units that do not chime a song or strike any kind of noise. The hour hand on most clocks are only a friction fit, therefore it is easy to point it in any direction with your hand one hour. The only risk really is the hour hand coming up some on its tube and touching the minute hand. This would make the clock stop and the hour hand too loose. The tube that the hour hand sits on tapers. Therefore, the lower the hour hand mount is on that tube the tighter it is. In usual circumstance this is not an issue -just moving it back an hour. Only if it is loose already and too high up on its shaft it could be the tipping point where you need to tighten it. The solution of course is to put it lower on its shaft by pressing on it as you wiggle it back and forth. This forces it deeper on the post. This would need to be done in a way that it is not so low it rubs the clock dial, as this would stop the clock. You may need to remove the minute hand entirely to provide access to the hour hand that you are trying to tighten. In the end you should have the dial / hour hand / minute hand all even and not touching each other or whatever glass cover.

Never go backward in time with these units, only go forward in time unless the movement is made in Germany. If it is a German made unit you can go backward, however know the strike count will be off at first, then it will correct itself. Most other mechanical time strike units have a wire hanging down behind the dial to your left of the hand shaft as you face the clock. This wire if lifted up would make the clock strike out the next hour, just keep hitting the wire up after it strikes fully and again until the clock is striking the hour before whatever it is now. If the clock does not have such a wire, it is possible to do this by getting to the back side of the clock movement itself. If the clock is spun around and the back removed, you will see the lowest and largest gears on either side, one side is the time and the other is the strike (this is the one on your right as you face the back of the clock movement.) Above this lowest and largest wheel on the strike side you will see an arm coming over it and then angling down into this wheels groove. All that is required to advance the hours is to lift this arm up and let it drop with fingers. It will go on to the half hour, bump it again to go through the next hour, and so on until it is striking the hour before whatever it is. At this point it is only needed to point the hour hand to the prior hour, and the clock is now adjusted for Daylight Savings.

There are three ways these can be set to be the hour prior and still have the chimes be in sync with the time. 1. Go backward = These units are fine to just go backward in time with the minute hand for one hour. The chimes may or may not be messed up for an hour, but will correct itself. This is fine to do and even recommended by the factories that produce them. 2. Go forward fast = Many clock owners may have it very ingrained into them to never go backwards, and this is true for some units, but not these. However for those who insist this is a bad idea, the following is the way the can be moved forward to get the same result. Spin the minute hand around and around for the 11 hours to be back where you were but an hour before. It is not required to wait for every quarterly chime to complete, it can go around and around fast with the minute hand it does not matter. The first hour of chimes maybe wrong but that is ok, it will be right the next time as it auto corrects itself. 3. Go forward slow = In this way there is no concern at all about messing up the chimes, they will be perfect without the hour wait. Just advance the minute hand one quarter at a time letting it chime fully before advancing to the next quarter. Do this for 11 hours and it is done, it will take awhile and it is not needed to do it this slow way, but is a valid option.

Same as all the above, however instead of advancing the time only 11 hours it will need to be advanced by 23 hours. This is because the clock will think it is night time when it is day, and therefore will not chime during the day but will all night long.

Do not go backwards with these units. Some are made to go backward and some are not, the best rule is to just go forward. This will keep the chime with the time correctly.
