This function is very simple to use, but if you want to find the first Monday of each month, Excel does not provide a direct function. So how do we solve this problem? Here we present a detailed tutorial on date functions to teach you how to use existing functions to easily calculate the first Monday of each month.<\/p>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--superbspacing-small)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"518\" height=\"257\" src=\"https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=518%2C257&#038;ssl=1\" alt=\"WEEKDAY\u65e5\u671f\u51fd\u6578\u6559\u5b78\" class=\"wp-image-873\" srcset=\"https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?w=518&amp;ssl=1 518w, https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=150%2C74&amp;ssl=1 150w, https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=300%2C149&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=230%2C114&amp;ssl=1 230w, https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=350%2C174&amp;ssl=1 350w, https:\/\/i0.wp.com\/www.fyndpro.com\/wp-content\/uploads\/2019\/07\/%E6%89%BE%E5%87%BA%E6%AF%8F%E6%9C%88%E7%AC%AC1%E5%80%8B%E6%98%9F%E6%9C%9F%E4%B8%80%E7%9A%84%E6%97%A5%E6%9C%9F.png?resize=480%2C238&amp;ssl=1 480w\" sizes=\"auto, (max-width: 518px) 100vw, 518px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">We can calculate the first Monday of each month with a formula. Below are the steps and the formula details:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Use the DATE function<\/strong>First, we need to generate the first day of each month. This can be done using the <code>DATE<\/code> function. For example,<code>DATE(\u5e74, \u6708, 1)<\/code> returns the first day of that year and month.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Combine with the WEEKDAY function<\/strong>Next, use the <code>WEEKDAY<\/code> function to determine which weekday that date falls on. For example,<code>WEEKDAY(DATE(\u5e74, \u6708, 1), 12)<\/code> returns a number indicating the weekday, where Tuesday = 1, Wednesday = 2, and so on, up to Monday = 7.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Calculate the date of the first Monday<\/strong>To find the first Monday of each month, we can use the following formula:<\/li>\n\n\n\n<li>This formula means subtracting the weekday number of that date from 8. The final result gives us the day of the month for the first Monday.<\/li>\n<\/ul>\n\n\n\n<pre class=\"wp-block-code\"><code>=8-WEEKDAY(DATE(B3,C3,1),12)<\/code><\/pre>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--superbspacing-small)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Detailed explanation of WEEKDAY<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>As for<code>WEEKDAY(DATE(B3,C3,1),12)<\/code>it is to find the parameter for June 1, 2019.<\/li>\n\n\n\n<li>For example, June 1, 2019 is a Saturday, so the result is 5, because that '12' causes Tuesday to be represented as 1, Wednesday as 2, ... Monday as 7.<\/li>\n\n\n\n<li>The mapping for that parameter can be referenced in the table below:<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter<\/th><th><strong>Return values<\/strong><\/th><\/tr><\/thead><tbody><tr><td>1 or omitted<\/td><td>Numbers 1 (Sunday) through 7 (Saturday).
