By the way, what are Rokuyo?

Rokuyo (六曜) refers to the six days of the week in the traditional Japanese calendar that indicate good or bad luck for each day. Specifically, there are six days: "Sensho", "Toyobiki", "Senbu", "Shakko", "Taian", and "Butsumetsu". Each day has a meaning that is said to be suitable for certain actions and events.

Sensho (先勝)

On this day, the morning is considered auspicious. It is recommended to act quickly to start something, and it is especially suitable for business negotiations and starting new projects. However, you should be careful as your luck will decrease from the afternoon onwards.

Tomobiki (友引)

This day is said to attract friends, and is ideal for celebrations such as weddings. It is also a good day for gatherings and events with friends. However, it is said to be avoided for funerals.

Senbu (先負)

It is auspicious from the afternoon onwards, and it is recommended to act carefully, especially in the morning. When making business or new plans, it is better to move your actions after the afternoon.

Shakko (赤口)

This is a day when you need to be especially careful, and it is important to be careful of fire. It is also said that it is better to avoid important decisions and contracts. It is recommended to spend this day calmly, as you may be short-tempered or get into trouble.

Taian (大安)

This is considered the most auspicious day, and it is said that you are likely to succeed in whatever you do. This is a great day for weddings and starting new businesses. It is also a good day to make special plans with friends and family.

Butsumetsu (仏滅)

This is considered the most unlucky day, and anything important should be avoided. It is best to avoid starting anything new on this day, and spend your time relaxing.

Summary

Incorporating Rokuyo into your daily life may help you make better decisions. Planning important events on Taian days and spending modestly on Butsumetsu days will give you a sense of security in terms of your mood and feelings.

Also, making plans to spend time with friends on Tomobiki days can be an opportunity to deepen your relationships. This type of use is a new approach to utilizing the wisdom of Rokuyo.

Differences Between Your Home Microwave’s Wattage and Packaged Foods

Ready-made lunches and frozen foods sold at supermarkets and convenience stores are extremely handy. On the package, you’ll usually find the recommended microwave wattage and heating time, such as “3 minutes at 500W” or “2 minutes 30 seconds at 600W.”

But what should you do if the wattage of your home microwave is different from the wattage shown on the package?

In reality, when your microwave’s wattage is different, the proper heating time also changes. For example, if you use the time listed for 600W on a 500W microwave, the food may end up undercooked. On the other hand, if you use the time listed for 500W in a 600W microwave, the food may be overheated. In either case, it becomes difficult to heat your food both safely and deliciously.

How to Deal With Different Wattages

There is a handy tool to solve this problem: the Microwave Wattage Converter app. Based on the wattage and heating time printed on the food package, this app automatically calculates the correct heating time for the wattage of your own microwave.

Using the app is very simple. First, select the wattage of your home microwave (for example, 500W or 600W). Next, enter or select the wattage and heating time listed on the package. The app will then automatically calculate the actual heating time you need. This way, you can heat your food for the optimal amount of time in your own microwave.

Summary

By using the Microwave Wattage Converter app, you can easily resolve differences between your home microwave’s wattage and the wattage printed on food packages. The app tells you the proper heating time without any complicated calculations, helping you avoid uneven heating or overheating.

Give it a try and make your daily life a little more convenient.
