What year is Showa 5? A child was born in 2012, but what year is Heisei? Have you ever had any problems when converting from the Western era to the Japanese era, or from the Japanese era to the Western era? This app can mutually convert from the Japanese era name to the Christian era, and from the Western calendar to the Japanese era name. The Japanese era name that can be converted is from Meiji to Reiwa. On the top screen of the app, tap the Japanese era name or the one you want to convert to the Western calendar and enter it. Please select the Japanese era name by scrolling and selecting the era name and the year. Please enter the number directly for the year. You can check the converted history by tapping the history button. If you register frequently used items such as the birthdays of your parents, children, and spouse as favorites, you can easily check them on the Favorites screen. The app icon is designed to represent this year's Japanese era and Western calendar. If you place the icon in an easy-to-see location when you start up your iPhone or iPad, you can always check the era name of this year. In the free version, you can create up to 1 favorite and check up to 2 histories. If you want to create unlimited favorites and check 100 records, please consider purchasing the premium version within the app. ---------------------- Terms of Use and Privacy Policy: https://akikibai-laboratory.jimdofree.com/privacy-policy/
