Tap a unit on the ladder to see how it fits the next size up. Check how many minutes are in an hour, hours in a day, days in a week, and months in a year. Open the month strip for 28 to 31 days and a leap-year note for February. Then practice which lasts longer, how many fit, and which month comes next. Progress stays in this browser.
Tap a unit, then drag. Clock hands, a day sky, seven day tiles, a calendar, or months around the sun.
hour
Hour 12, 0 minutes
Drag the short blue hand. The long hand still shows minutes inside that hour.
Drag the long rose hand for minutes. Drag the short blue hand for hours.
An hour is 60 minutes. You can also read hours on an analog clock face.
1 hour = 60 minutes
Tap a month to see how many days it usually has.
January has 31 days.
A leap year adds 29 February so the calendar stays lined up with Earth's year. Common years use 28 February.
Exact fills, honest months, leap years, practice games, and the clock tool.
The unit buttons are large enough for a child to tap on an iPad. Tap Explore or Practice once after the page loads to unlock the short chime. Keep media volume up. Portrait mode keeps the ladder and month grid fully on screen.
Sixty minutes make one hour, 24 hours make one day, 7 days make one week, and 12 months make one year. Those counts are exact. A month is not exactly four weeks. Months have 28 to 31 days, so the tool never asks you to treat four weeks as a month.
Tap a month to see its usual day count. February has 28 days in a common year and 29 days in a leap year, which happens every four years in the Gregorian calendar, with century-year exceptions. The leap toggle is a teaching note, not a calendar of a real date.
Explore is for looking: tap units, change the fill count, and walk the 12 months. Practice has three games. Which lasts longer includes some equal pairs, such as 60 minutes and 1 hour. How many uses the exact fills. Next month wraps December to January.
Start on the ladder with hour and day before months. Say the fill out loud: two hours is 120 minutes. When a child says a month is four weeks, open February and April and compare day counts. Pair this page with the analog clock tool for minutes on a face.
If there is no sound, tap Explore or a unit once. If the grid looks cramped, rotate to portrait and scroll. Clearing site data for this site resets the practice counts. A home tablet and a school laptop keep separate logs.
Free tools that often go together. Everything runs in your browser.
It is a free browser practice tool for the names and sizes of everyday time units. In Explore you tap a ladder from minute to year, see exact fills such as 60 minutes in an hour, and open a 12-month strip with day counts. February can show 28 or 29 days with a leap-year note. Practice asks which of two amounts lasts longer, how many smaller units fit in a larger one, and which month comes next. There is no account. Correct and attempt counts stay in this browser only. It does not read analog clock hands. That job lives on Learn to Read a Clock.
Kids often mix two different skills: reading a clock face, and knowing that a week is seven days. Worksheets sometimes print 4 weeks = 1 month, which is not true. This page keeps those ideas apart. Exact fills (60, 24, 7, 12) get a number game. Months get a strip with 28 to 31 days so February and April look different. Equal pairs such as 60 minutes and 1 hour teach that two names can mean the same length. Short checks with a miss that stays put beat a long mixed worksheet.
A minute is the smallest unit on this ladder. Sixty minutes make an hour. Twenty-four hours make a day. Seven days make a week. Twelve months make a year. A month sits between a week and a year, but it is not a fixed number of weeks. That is why the fill buttons skip month. You can still compare one month with one week: a month lasts longer. Two weeks still last less than one month, because even February has 28 days.
Four weeks are 28 days. Some months have 30 or 31 days, so they are longer than four weeks. February has 28 days in a common year, which matches four weeks, and 29 days in a leap year. Teaching 4 weeks = 1 month hides that spread. This tool shows each month's day count instead, and never uses four weeks as a month in the How many game.
A leap year adds one extra day so the calendar stays lined up with Earth's trip around the Sun. On this page that extra day is 29 February. Common years use 28 February and 365 days. Leap years use 366 days. The usual pattern is every four years, with some century years skipped. The leap toggle is only for teaching February. It is not a birthday calculator and it does not score leap-year rules.
Which lasts longer shows two amounts. Pick the longer one, or Same when they match, such as 24 hours and 1 day. How many asks for an exact fill, such as how many minutes are in 2 hours. Next month asks what follows a named month, wrapping December to January. A miss keeps the question so you can try again. A correct answer loads a new one. Each game keeps its own counts in this browser.
No. The clock tool is a practice game: drag the blue hour hand and the rose minute hand to match a time such as 3:15, then check. This page is for unit names and how long they last. Explore here also has a teaching clock, so you can drag minutes into an hour, then hours across a day sky. It does not score a target time. Use the clock link when you want to match 3:15. Use this page for days, weeks, months, and years.
It is for children first learning the calendar and for anyone who wants a calm refresh of 60, 24, 7, and 12. Parents can sit beside a child, stay in Explore on hours and days, then try Which lasts longer. Counts are stored in local storage on this browser only. Nothing is uploaded. A private window, another device, or clearing site data starts a fresh log. It does not teach time zones, 24-hour digital time such as 13:00, or elapsed-time word problems.
