Classes is named by BEM methodology

<div class="syotimer">
    <div class="syotimer__head"></div>
    <div class="syotimer__body">
        <div class="syotimer__item syotimer-cell syotimer-cell_type_day">
            <div class="syotimer-cell__value">1</div>
            <div class="syotimer-cell__unit">day</div>
        <div class="syotimer__item syotimer-cell syotimer-cell_type_hour">
            <div class="syotimer-cell__value">1</div>
            <div class="syotimer-cell__unit">hour</div>
        <div class="syotimer__item syotimer-cell syotimer-cell_type_minute">
            <div class="syotimer-cell__value">1</div>
            <div class="syotimer-cell__unit">minute</div>
        <div class="syotimer__item syotimer-cell syotimer-cell_type_second">
            <div class="syotimer-cell__value">1</div>
            <div class="syotimer-cell__unit">second</div>
    <div class="syotimer__footer"></div>

Example of css styles for syotimer in resources/default.css.


Option Description Type of Value Default Value Available Values
year year of date, which should count down timer integer 2014 >1979
month month of date, which should count down timer integer 7 1-12
day day of date, which should count down timer integer 31 1-31
hour hour of date, which should count down timer integer 0 0-23
minute minute of date, which should count down timer integer 0 0-59
second second of date, which should count down timer integer 0 0-59
layout sets an order of layout of units of the timer: days (d) of hours ('h'), minute ('m'), second ('s'). string 'dhms'
timeZone setting the time zone of deadline. If 'local' then the time zone is ignored and the deadline is determined by local time of the user. Otherwise, specifies the offset from the UTC float/string 'local' 'local', >-12 && <12
ignoreTransferTime If true then transfer to summer/winter time will not be considered. For details, see "About summer/winter time" boolean false
doubleNumbers true - show hours, minutes and seconds with leading zeros (2 hours 5 minutes 4 seconds = 02:05:04) boolean true
effectType The effect of changing the value of seconds string 'none' 'none', 'opacity'
lang localization of a countdown signatures (days, hours, minutes, seconds) string 'eng' see "Localization"
periodic true - the timer is periodic. If the date until which counts the timer is reached, the next value date which will count down the timer is incremented by the value periodInterval boolean false
periodInterval the period of the timer in periodUnit (if periodic is set to true) integer 7 >0
periodUnit the unit of measurement period timer string 'd' 'd', 'h', 'm', 's'


The use of the methods has the following syntax:

$('.your_selector_to_countdown').syotimer(nameOfMethod, param1, param2, ... , paramN);


setOption - assigns a value to the option


  1. Name of option
  2. Value

Code examples:

$('.your_selector_to_countdown').syotimer('setOption', 'effectType', 'opacity');


Default languages

By default the supported plugin languages:

Language Value of lang option
English 'eng'
Russian 'rus'
Spanish 'spa'
Portuguese 'por'
Hebrew 'heb'

Adding new language

It is very simple to execute localization of a plugin under the language. You need to add the translations of signatures to timer elements as the parameter of an object of $.syotimerLang. Then you need determine a new language in the syotimer options. For example we will add support of Spanish (though this language is supported by default):

$ = {
    seconds: ['segundo', 'segundos'],
    minute: ['minuto', 'minutos'],
    hour: ['hora', 'horas'],
    day: ['dia', 'dias']

    lang: 'spa'

Inducement of a noun after a numeral

At the majority of languages a simple algorithm of determination of inducement of a noun after a numeral. If numeral is equal 1 then need input first element from array. Otherwise - second element.

But there are languages in which more difficult rules of determination of the correct inducement of nouns after a numeral (for example, Russian).

For example, consider a completely synthetic language (let it be called "Nenglish"). It is very similar to English but there are significant differences in the spelling of nouns after numerals. Namely, the difference in the suffixes of these nouns:

  • if the number ends with the digit 1 then to the noun added the suffix "one" (21 secondone, 1 minuteone, ...);
  • if the number ends with the digit 5 then the suffix is equal "five" (35 hourfive, 5 secondfive);
  • otherwise the suffix is equal to "s" (24 minutes, 3 days).

To add a Nenglish in Syotimer need first add all possible variants of a writing of the captions of the items of the plugin. The abbreviated name of the language will take "neng":

$.syotimerLang.neng = {
    second: ['secondone', 'secondfive', 'seconds'],
    minute: ['minuteone', 'minutefive', 'minutes'],
    hour: ['hourone', 'hourfive', 'hours'],
    day: ['dayone', 'dayfive', 'days'],
    handler: 'nengNumeral'

The "handler" must contain a name of method that receive the one argument is a number. This method should return the array index that determines the correct variant of the noun:

$.syotimerLang.nengNumeral = function(number) {
    var lastDigit = number % 10;
    if ( lastDigit === 1 ) {
        return 0;
    } else if ( lastDigit === 5) {
        return 1;
    } else {
        return 2;

Then only have to specify the language when you create the instance Syotimer:

    lang: 'neng'

About summer/winter time

In some countries, there are the division between summer and winter time. This artifact may affect the correct operation of the countdown when the difference between the current time and the deadline is very large.

For example, used a timer with a period of one day, for which the deadline set on the winter time. Then for users from New York in the summer this timer will produce an error for 1 hour.

To exclude these cases set ignoreTransferTime to false.
