The miscellaneous section collects general-purpose tools that do not fit the other categories. The time zone converter compares the time in up to eight zones with a main zone, picked on a timeline in 30-minute steps, and lets you search by abbreviation, UTC offset or IANA zone name. The lunar calendar shows the Moon phase and the illuminated percentage of the lunar disc for each day of a period of up to 60 days, starting on any date from 1900 onwards, with an illustrated chart and a day-by-day table. The Chinese calendar converts any date between January 31, 1900 and January 28, 2101 between the Gregorian calendar and the traditional Chinese lunisolar calendar, in both directions. The barbecue calculator estimates how much meat, side dishes, drinks, charcoal and ice to buy for a barbecue, based on the guests and the duration of the party. You will also find the fuel cost calculator, which compares trips and ethanol versus gasoline, the appliance electricity cost calculator, and the Chinese kinship term calculator, which names any relative in Mandarin from a chain of relationships.
Use the lunar calendar to plan stargazing or night photography and to see when the next full moon is due; its phases come from a mean lunar-cycle model, so a phase change may be up to about a day away from the exact astronomical moment. Use the Chinese calendar to find the lunar date of a birthday, the Chinese New Year, festivals such as the Mid-Autumn Festival, the 24 solar terms and the zodiac year, with an almanac page, a month view and the zodiac wheel. All of them are free and need no sign-up.
