Chrome extensions for daily life: lunar dates and maps
Small everyday lookups break your flow: converting a lunar birthday, checking how many days until the next Korean holiday, or copying coordinates out of one map site to reopen them in another. Lifestyle extensions keep those answers in a toolbar popup instead of a new tab and a search.
1 of 2 are live on a store.
What to look for
Prefer the ones that work offline
Lunar-solar conversion and fixed holiday dates are arithmetic, not live data, so a calendar extension can do all of it inside the popup. Lunar Calendar declares only the storage permission and no host access, which is what an offline calculator should look like. If a date tool wants network access, it is worth asking what it is fetching.
A single-site tool should be scoped to that site
Check the content script matches before you install anything that adds a panel to a specific website. Naver Map Coords injects only on map.naver.com and declares no permissions at all; a helper for one site that matches *://*/* can read every page you open instead. The store listing's permission summary tells you which one you are getting.
Clipboard and new tabs need no special access
Copying a coordinate string and opening another map in a new tab are both things an extension can do without extra permissions. So if a map or calendar utility requests reading your browsing history, tab activity, or all site data, the request is doing something other than the feature you came for.
Bundled Korean data has an expiry date
Holiday tables shipped inside an extension cover the fixed solar and lunar holidays, but a substitute holiday or a one-off national holiday announced during the year will not be in them. Treat a countdown badge as a convenience, not as the source of truth for booking flights. Check the extension's update date before you plan around it.
Questions people ask
How do I convert a lunar date to a solar date in Chrome?
Use a calendar extension that does the conversion in its popup, like Lunar Calendar in this category. You type a lunar date and get the matching solar date without leaving the page you were on. Because the conversion is arithmetic, it also works with no internet connection.
Do lifestyle extensions need access to all the sites I visit?
Almost never. Lunar Calendar runs on storage alone, and Naver Map Coords declares no permissions and only loads its script on map.naver.com. Before installing anything in this category, compare the permission list to the one thing you want it to do, and skip it if the list is longer.
Can I open a location from Naver Map in Google Maps or Kakao Map?
Yes. Naver Map Coords reads the map centre's latitude and longitude from the map.naver.com URL and gives you buttons to open the same point in Kakao Map or Google Maps in a new tab. It can also copy the coordinates as "lat,lng" to your clipboard, and the address when Naver exposes it on the page.
Can I see upcoming Korean holidays and the 24 solar terms as well?
Yes. The Lunar Calendar popup lists the holidays still ahead with the days remaining, alongside the 24 solar terms, and shows today's solar date, lunar date and current term on the same screen. Temporary public holidays designated part-way through a year may not be included, so check an official calendar before booking anything around one.
