The '*' character is used to specify all values. For example, "*" in the minute field means "every minute". 
“*”字符被用来指定所有的倹{€‚如åQ?#8221;*“在分钟的字段域里表示“每分é’?#8221;ã€?nbsp;
The '?' character is allowed for the day-of-month and day-of-week fields. It is used to specify 'no specific value'. This is useful when you need to specify something in one of the two fileds, but not the other. See the examples below for clarification. 
“?”字符只在日期域和星期域中使用。它被用来指å®?#8220;非明¼‹®çš„å€?#8221;。当你需要通过在这两个域中的一个来指定一些东西的时候，它是有用的。看下面的例子你ž®×ƒ¼šæ˜Žç™½ã€?nbsp;
月䆾中的日期和星期中的日期这两个元素时互斥的一起应该通过讄¡½®ä¸€ä¸ªé—®å??)来表明不惌™®¾¾|®é‚£ä¸ªå­—ŒD?br />
The '-' character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12". 
“-”字符被用来指定一个范围。如åQ?#8220;10-12”在小时域意味着“10炏V€?1炏V€?2ç‚?#8221;ã€?nbsp;

The ',' character is used to specify additional values. For example "MON,WED,FRI" in the day-of-week field means "the days Monday, Wednesday, and Friday". 
“,”字符被用来指定另外的倹{€‚如åQ?#8220;MON,WED,FRI”在星期域里表½C?#8221;星期一、星期三、星期五”. 

The '/' character is used to specify increments. For example "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". Specifying '*' before the '/' is equivalent to specifying 0 is the value to start with. Essentially, for each field in the expression, there is a set of numbers that can be turned on or off. For seconds and minutes, the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to 31, and for months 1 to 12. The "/" character simply helps you turn on every "nth" value in the given set. Thus "7/6" in the month field only turns on month "7", it does NOT mean every 6th month, please note that subtlety. 

The 'L' character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "last", but it has different meaning in each of the two fields. For example, the value "L" in the day-of-month field means "the last day of the month" - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means "7" or "SAT". But if used in the day-of-week field after another value, it means "the last xxx day of the month" - for example "6L" means "the last friday of the month". When using the 'L' option, it is important not to specify lists, or ranges of values, as you'll get confusing results. 

Læ˜?#8216;last’的省略写法可以表½Cºday-of-monthå’Œday-of-week域，但在两个字段中的意思不同，例如day-of-month域中表示一个月的最后一天，
如果在day-of-week域表½C?#8216;7’或è€?#8216;SAT’åQŒå¦‚果在day-of-week域中前面加上数字åQŒå®ƒè¡¨ç¤ºä¸€ä¸ªæœˆçš„最后几天，例如‘6L’ž®Þp¡¨½CÞZ¸€ä¸ªæœˆçš„最后一ä¸?br /> 星期五，

The 'W' character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify "15W" as the value for the day-of-month field, the meaning is: "the nearest weekday to the 15th of the month". So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. However if you specify "1W" as the value for day-of-month, and the 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not 'jump' over the boundary of a month's days. The 'W' character can only be specified when the day-of-month is a single day, not a range or list of days
. 
The 'L' and 'W' characters can also be combined for the day-of-month expression to yield 'LW', which translates to "last weekday of the month". 

The '#' character is allowed for the day-of-week field. This character is used to specify "the nth" XXX day of the month. For example, the value of "6#3" in the day-of-week field means the third Friday of the month (day 6 = Friday and "#3" = the 3rd one in the month). Other examples: "2#1" = the first Monday of the month and "4#5" = the fifth Wednesday of the month. Note that if you specify "#5" and there is not 5 of the given day-of-week in the month, then no firing will occur that month. 

The 'C' character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "calendar". This means values are calculated against the associated calendar, if any. If no calendar is associated, then it is equivalent to having an all-inclusive calendar. A value of "5C" in the day-of-month field means "the first day included by the calendar on or after the 5th". A value of "1C" in the day-of-week field means "the first day included by the calendar on or after sunday".
