Tomb-sweeping day is coming, some people were surprised to find that, this year′s calendar is the Ching Ming Festival on April 4. "Tomb-sweeping day is not April 5? What a day earlier this year? "Meteorological experts said the Tomb as a solar term is not fixed on a particular day, but associated with the Earth′s revolution. Tomb Sweeping Festival typically occurs annually on April 4 in the 6th day.

Why Ching Ming Festival dates will "run"? Weather Bureau senior engineer Zhang Mingying, introduction, tomb-sweeping day is only the solar terms festival days, its date is not in accordance with the time, but according to the longitude of the Sun is calculated. Zhang Mingying explain Earth′s revolution around the Sun approximately 365 days a week, running line is known as the ecliptic orbits of the Earth. Ecliptic longitude is the longitude on the ecliptic coordinates of measurement. According to the practice of astronomy, solar longitude starting with the vernal equinox measured from West to East, 360 degrees. 360 degrees of longitude of the Sun the ancients divided into 24 equal pieces, each 15 degrees, as a solar term. Between two throttle for about 15 days apart, and has merged all year round.

When the Ching Ming Festival, the Earth to the Sun yellow 15 degrees. However, due to the Earth 365 days of a week is not necessarily strict, and may also occur in the solar Division of the date is not fixed. Under normal circumstances, about 15 days after the spring equinox is the clear, specific dates before and after the changes of no more than three days.

Festival dates are not fixed, also make the long weekend holidays there are some changes. In fact, China′s Tomb-sweeping day holiday for 1 day, and even at the weekend on a paid leave policy makes clear the long weekend a 3-day holiday. For public holiday overtime, are you a holiday "day" working overtime can be related to how much you get paid wages.

Beijing meaning Yin lawyer firm Director Huang l p lawyer introduced, according to China labor law provides, paid overtime of specific standard is: in standard days within arrangements workers extended work time of, paid not below day wage 150% of wage paid; statutory rest day arrangements workers work and cannot arrangements compensatory of, paid not below day wage 200% of wage paid; statutory holiday arrangements workers work of, paid not below day wage of 300% of wage paid.

Under this provision, to Ching Ming Festival holidays this year as an example, April 4 for the tomb-sweeping day, on April 4 overtime are paid no less than the wage 300%, on April 2, 3rd weekend two days of overtime will receive no less than the wage 200% reward.

清明节即将到来，一些市民惊奇地发现，今年日历上的清明节是4月4日。“清明节不都是4月5日吗？怎么今年提前了一天？”气象专家称，清明作为一个节气，并不固定在某一天，而是跟地球公转有关。清明一般会出现在每年4月4日至6日中的一天。

为什么清明节的日期会“前后跑”？市气象局高级工程师张明英介绍，清明节是惟一既是节气又是节日的日子，它的日期不是按照时间，而是按照太阳黄经来进行计算的。张明英解释，地球绕太阳公转一周约365天，地球的公转运行线路就称为黄道。黄经是黄道上的经度度量坐标。按天文学惯例，太阳黄经以春分点为起点自西向东度量，分360度。古人把太阳黄经的360度划分成24等份，每份15度，为一个节气。两个节气间相隔日数为15天左右，全年即有二十四节气。

清明节气时，地球公转到达太阳黄经15度位置。但是由于地球公转一周的时间不一定是严格的365天，所以在节气的划分上也可能出现日期不固定的现象。一般情况下，每年春分后15天左右即为清明，具体日期前后变动不超过三天。

清明节的日期不固定，也使小长假的休假日存在一定变化。事实上，我国的清明节法定节假日为1天，与相邻周末的连休调休政策使得清明小长假出现3天假期。对于假期加班的市民，是不是在法定节假日“正日子”加班，可关系到获得工资报酬的多少。

北京义贤律师事务所主任黄乐平律师介绍，根据我国劳动法规定，支付加班费的具体标准是：在标准工作日内安排劳动者延长工作时间的，支付不低于日工资150%的工资报酬；法定休息日安排劳动者工作又不能安排补休的，支付不低于日工资200%的工资报酬；法定节假日安排劳动者工作的，支付不低于日工资的300%的工资报酬。

在此规定下，以今年清明节假期为例，4月4日为清明节，因此在4月4日加班可获得不低于日工资300%的报酬，而在4月2日、3日周末这两天加班则可获得不低于日工资200%的报酬。
