Wore my HRM for a day, is that an accurate number for TDEE?

I wore my heart rate monitor yesterday from about 9:30 am- 8:30 pm. I was up at 7 am and didn't go to bed until 11 but I wanted to get an idea of how many calories I burn in a day. I don't see why this would be inaccurate since I use it to measure my calories burned during exercise and it lines up with the calculations MFP gives. However I was surprised to see 2120 as my cals burned. Now, I did do 70 minutes of yoga which based on previous weeks burned around 300 cals. I also breastfeed so that is anywhere between 300-600 calories a day and I am a very active momma always on the go and constantly cleaning my house. I would say yesterday is an example of a typical day.

My questions are two part. Is this an accurate way to get my TDEE number? Or should it be a little higher to account for the hours I was up and not wearing the hrm?

Please be kind to me, if you have a snide or snotty comment can you keep it to yourself please? I know the TDEE questions are endless so if you don't want to help me out just move along. Thanks.

    Are you wanting to lose or maintain? If that is your daily schedule I would think it would be a good starting point. I have a polar hrm and I love it. I have continually lost weight going by the calorie burn so i would trust mine. You could try it for a month and see if you maintain your weight. Maybe weigh yourself and measure and then put the scales and tape away for a month, eat according to your hrm and see what happens. Best of luck!

    I'm wanting to lose weight. I have my calorie goal set at 1628 or something right around there.

    Wearing a HRM all day is not an accurate count of calories burned. They are simply not designed for that.

    ^This. The algorithms HRMs use do not give accurate calorie calculations except during steady state cardio at a fair intensity. They overestimate burns during low intensity exercise, such as walking, and are not designed to determine calorie burns while sedentary where they would be even worse.

    Interesting. I use my HRM primarily for tracking my walking and it's calculations line up closely with MFP's calculations so I think with my monitor it is pretty darn accurate in terms of low intensity exercises. Although my walks are at a brisk pace so I don't know if that is technically low intensity.

    I just did my TDEE calculations on another site and those numbers aligned with the daily caloric burn I did that day too. So I'm thinking it may have been pretty accurate afterall.
