1.a calendar based on solar cycles
solar calendar (n.)
If the position of the earth in its orbit around the sun is reckoned with respect to the equinox, the point at which the orbit crosses the celestial equator, then its dates accurately indicate the seasons, that is, they are synchronized with the declination of the sun. Such a calendar is called a tropical solar calendar.
The following are tropical solar calendars:
The Zoroastrian calendar is a religious calendar used by adherents of the Zoroastrian faith, and is an approximation of the tropical solar calendar.
If the position of the earth (see above) is reckoned with respect to the fixed stars, then the dates indicate the zodiacal constellation near which the sun can be found. Such a calendar is called a sidereal solar calendar.
The mean calendar year of such a calendar approximates the sidereal year.
Indian calendars like the Hindu calendar, Bengali calendar, Malayalam calendar and Tamil calendar are sidereal solar calendars. The Thai solar calendar, based on the Hindu solar calendar is also a sidereal calendar. They are calculated on the basis of the apparent motion of the sun through the twelve zodiacs rather than the true tropical movement of the earth.
Lunisolar calendars may be regarded as solar calendars, although their dates additionally indicate the moon phase. Because a typical lunisolar calendar has a year made up of a whole number of lunar months, it can't indicate the position of Earth on its revolution around the sun as well as a pure solar calendar can.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
