Number Battle
Hit start and out-multiply the clock. Every card is a month in disguise — read the calendar, then fire. The game reads you back: score high and it promotes you.
The Skill Yard
One deck of months, six ways to drill it. Pick a game, beat the 60-second clock, and climb from Private to General. Each game tracks its own rank, so everyone trains at their level.
Find the month that completes the equation.
Every number
is a month in disguise.
Instead of cold digits, each card wears a month of the year. Kids read the calendar — July is the 7th month, so July is 7 — then multiply or add. Language and math working the same problem, so word-lovers and number-lovers both get a foothold.
-
1
Read the month
See “July.” Count the calendar — it's the 7th month. The picture is the clue; the number is hiding underneath.
-
2
Battle the values
Two months flip. Multiply them — July × April is 7 × 4 — and the first to shout 28 wins both cards.

3
Wilds add up
At General rank, a WILD flips the round to addition — July 7 + Days in October 31 = 38 — so products never get out of hand.
Twelve months, one number each.
Read the calendar in order and every value falls into place. The cards are grouped by season — learn them a quarter at a time and you'll read the whole deck on sight.
WILD Cards
The stories behind the months.
Every month carries real history — gods, emperors, harvests and holidays. Tap a number to read where its name came from and why it lands where it does on the calendar.
1January
Named for Janus, the Roman god of beginnings and transitions, January looks both backward and forward. It became the first month after Julius Caesar's calendar reform in 45 BCE, and today it still stands for renewal — resolutions, fresh starts, and planning the year ahead.
2February
February takes its name from Februa, an ancient Roman festival of purification. Once the last month of the Roman year, it now sits second — the shortest month, tied in modern culture to Valentine's Day and Black History Month.
3March
Named after Mars, the Roman god of war, March opened the original Roman calendar and signaled readiness for spring campaigns and planting. In the Northern Hemisphere it still marks the start of spring — growth, renewal, and getting moving again.
4April
April likely comes from the Latin aperire, "to open," for the blossoming of flowers and trees. Dedicated to Venus in Roman times, it carries a legacy of renewal that lives on today in events like Earth Day.
5May
May honors Maia, a Roman goddess of growth and fertility. Historically the height of spring and the farming cycle, it still means growth and celebration — from Mother's Day to spring festivals around the world.
6June
June is named for Juno, Roman goddess of marriage and family — long considered a lucky time for weddings. Marking the start of Northern summer, it still centers on love and celebration, with weddings, Pride Month, and the summer solstice.
7July
July was named for Julius Caesar in 44 BCE, honoring his calendar reforms. A Roman season of harvest prep and summer festivals, it's now tied to independence celebrations, vacations, and the peak of summer.
8August
August was renamed for Emperor Augustus in 8 BCE to mark his achievements. A time of successful harvests in the Roman calendar, it now signals the culmination of summer and the run-up to the new school year.
9September
From the Latin septem, "seven," September was the seventh month before calendar reforms bumped it to ninth. Historically a harvest and thanksgiving season, it still marks the turn from summer to autumn and the start of the academic year.
10October
From the Latin octo, "eight," October was the eighth month originally, then became the tenth. A season of harvest festivals and winter prep, it's now known for Halloween and Oktoberfest.
11November
From the Latin novem, "nine," November closed out the harvest in the Roman year. Today it's a month of gratitude and reflection — Thanksgiving in the U.S. and Remembrance Day in many countries.
12December
From the Latin decem, "ten," December ended the original Roman calendar. Home to Saturnalia and the winter solstice, it stays festive today with Christmas, Hanukkah, and New Year's Eve.
24Hours in a Day
The 24-hour day traces back to Egyptian sundials and star charts, dividing time by astronomical observation. It remains the cornerstone of global timekeeping and our daily rhythm.
52Weeks in a Year
Splitting the year into 52 weeks grew out of Babylonian and Roman calendar systems aligning lunar cycles with farming. Today the 52-week structure underpins work schedules, school years, and fiscal planning.
31Days in October
October's 31 days were set in the Julian calendar to balance the solar year. Historically packed with festivals like Samhain — a forerunner of Halloween — it bridges harvest and winter.
365Days in a Year
The 365-day year is based on Earth's orbit around the sun, standardized by Egyptian astronomers and refined under Julius Caesar. It still anchors global timekeeping and our connection to natural cycles.
